In the first term of my Calculus, I had a hard time to review all my previous Math subjects, like Trigonometry and Algebra. I don’t have any idea in Calculus; I just know that it’s harder and more complicated than my previous Math subjects. After the midterm of this Semester I somehow know what Calculus for is, I learned that Differential Calculus can be use in finding the change in ratio. I also know that Calculus can be use to find the maximum and minimum rate of objects. It can also apply in other situation that involve changing and math. Using the concept of function derivatives, it studies the behavior and rate on how different quantities change. Using the process of differentiation, the graph of a function can actually be computed, analyzed, and predicted.

Though it is complicated to use well, calculus does have a lot of practical uses - uses that you probably won't comprehend at first. The most common practical use of calculus is when plotting graphs of certain formulae or functions. Using methods such as the first derivative and the second derivative, a graph and its dimensions can be accurately estimated. These 2 derivatives are used to predict how a graph may look like, the direction that it is taking on a specific point, the shape of the graph at a specific point (if concave or convex), just to name a few. When do you use calculus in the real world? In fact, you can use calculus in a lot of ways and applications. Among the disciplines that utilize calculus include physics, engineering, economics, statistics, and medicine. It is used to create mathematical models in order to arrive into an optimal solution. For example, in physics, calculus is used in a lot of its concepts. Among the physical concepts that use concepts of calculus include motion, electricity, heat, light, harmonics, acoustics, astronomy, and dynamics. In fact, even advanced physics concepts including electromagnetism and Einstein's theory of...

...Calculus
is the mathematical study of change,[1] in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integralcalculus (concerning accumulation of quantities and the areas under curves); these two branches are related to each other by the fundamental theorem ofcalculus. Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-definedlimit. Calculus has widespread uses in science, economics, and engineering and can solve many problems that algebra alone cannot.
Calculus is concerned with comparing quantities which vary in a non-linear way. It is used extensively in science and engineering since many of the things we are studying (like velocity, acceleration, current in a circuit) do not behave in a simple, linear fashion. If quantities are continually changing, we need calculus to study what is going on.

...How the calculus was invented?
Calculus, historically known as infinitesimal calculus, is a mathematical discipline focused on limits, functions, derivatives, integrals, and infinite series. Ideas leading up to the notions of function, derivative, and integral were developed throughout the 17th century, but the decisive step was made by Isaac Newton and Gottfried Leibniz. Publication of Newton's main treatises took many years, whereas Leibniz published first (Nova methodus, 1684) and the whole subject was subsequently marred by a priority dispute between the two inventors of calculus.
Greek mathematicians are credited with a significant use of infinitesimals. Democritus is the first person recorded to consider seriously the division of objects into an infinite number of cross-sections, but his inability to rationalize discrete cross-sections with a cone's smooth slope prevented him from accepting the idea. At approximately the same time, Elea discredited infinitesimals further by his articulation of the paradoxes which they create.
Antiphon and later Eudoxus are generally credited with implementing the method of exhaustion, which made it possible to compute the area and volume of regions and solids by breaking them up into an infinite number of recognizable shapes.
Archimedes of Syracuse developed this method further, while also inventing heuristic methods which resemble modern day concepts somewhat. (See...

Calculus:
Calculus (Latin, calculus, a small stone used for counting) is a branch of mathematics focused on limits, functions, derivatives, integrals, and infinite series. This subject constitutes a major part of modern mathematics education. It has two major branches, Differential Calculus and Integral Calculus, which are related by the fundamental theorem of calculus.
Calculus is the study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. A course in calculus is a gateway to other, more advanced courses in mathematics devoted to the study of functions and limits, broadly called mathematical analysis. Calculus has widespread applications in science, economics, and engineering and can solve many problems for which algebra alone is insufficient.
Application of Calculus in Various Fields:
Calculus is used in every branch of the physical sciences, actuarial science, computer science, statistics, engineering, economics, business, medicine, demography, and in other fields wherever a problem can be mathematically modeled and an optimal solution is desired. It allows one to go from (non-constant) rates of change to the total change or vice versa, and many times in studying a problem we know one and are trying to find...

...Marketing: A Field of Superb Minds
A deep realization about marketing begins its existence when I was browsing on the Internet. An author named Seth Godin captures my oblivious being in view of marketing with an aphorism that goes this way, “marketing is a contest for people’s attention”. This line must be too short to consider but it carries a lot of denotations which could be branched out to many ideas. Thinking, with respect to my instructor’s introduction of Marketing Management, I was near to set store by shifting my present course into that course, his field of expertise. But he, himself alone enlightened me enough to consider that he was just “marketing” the course.
As I was going-over the lecture done through online, I can say, marketing is interesting. Like what Godin defined, it is a contest, so it is a battle of creative minds to produce and innovate products, services, ideas, places, even experiences and many more. I find these marketers (the people who seek response from another party) brilliant for they possess superb brainpower to make the marketed things more attention-grabbing thus creates a greater number of customers to buy. While the country is always seeking out for demands, the marketers have to pursue to influence the level, timing and composition of demand to meet the objectives. They should mount and maintain organization by keeping and following the marketing system wherein the...

...THE HISTORY OF CALCULUS
The discovery of calculus is often attributed to two men, Isaac Newton and Gottfried Leibniz, who independently developed its foundations. Although they both were instrumental in its creation, they thought of the fundamental concepts in very different ways. While Newton considered variables changing with time, Leibniz thought of the variables x and y as ranging over sequences of infinitely close values. He introduced dx and dy as differences between successive values of these sequences. Leibniz knew that dy/dx gives the tangent but he did not use it as a defining property. On the other hand, Newton used quantities x' and y', which were finite velocities, to compute the tangent. Of course neither Leibniz nor Newton thought in terms of functions, but both always thought in terms of graphs. For Newton the calculus was geometrical while Leibniz took it towards analysis.
It is interesting to note that Leibniz was very conscious of the importance of good notation and put a lot of thought into the symbols he used. Newton, on the other hand, wrote more for himself than anyone else. Consequently, he tended to use whatever notation he thought of on that day. This turned out to be important in later developments. Leibniz's notation was better suited to generalizing calculus to multiple variables and in addition it highlighted the operator aspect of the derivative and integral. As a result, much of...

...The Simple Ledger: Ledger Accounts
You will now learn the system used to maintain an up to date financial position.
They use an account and ledger.
Account:
Page specially used to record financial changes
There is one account for each different item affecting the financial position. (Bank, equipment, automobile…)
Ledger:
All the accounts together are called the ledger
Group or file of accounts
Used to record business transaction and keep track of the balances in each specific account
If you wanted to know how much cash the business has to write a cheque, you would look in the ledger (Cash Account)
If you wanted to know how much the business owes on a bank loan, you would look in the ledger (Bank Loan Account)
A ledger can be prepared in different ways (cards, looseleaf ledger, computer system)
T-account:
Simple type of account. (A quick and easy way to track what is happening in each account)
Accounting form we use to keep track of the specific balance in an account
Shaped like a “T”
The formal account, the one actually used in business, will be introduced at a later time.
Important Features of Ledger Accounts
1. Each individual balance sheet item is given its own specially divided page with the name of item at the top (for now think of each “T” as a page)
Each of these pages is called an account
You must learn to call each one by name. i.e., cash account, bank loan account, and so on.
2. The dollar figure for each item is...
