History of Trigonometry
The History of Trigonometry dated back to the early ages of Egypt and Babylon. Many different Astronomers and Mathematicians all took place in helping create Trigonometry, people from Hipparchus, all the way to Isaac Newton. They all contributed a little something, something to formulate what we know as trigonometry. The places these events took place in different place like Greece and India, to Sweden to Germany. Trigonometry was formulated for computations in astronomy. A Greek Astronomer by the name of Hipparchus compiled the trigonometric table which measured the length of the chord subtending the various angles in a circle of a fixed radius r. In other words, Hipparchus made the first piece of the puzzle for the Unit Circle. His table was done in increasing degrees of 71.

Another man, buy the name of Ptolemy took that piece of the puzzle and created a table of chords which increased in 1 degree, this took place in the 5th century. This next piece was known as Menelaus’s theorem which formed the foundation of trigonometric studies for the next 300 years. Aroud that same time, an Indian mathematician took the chords out and replaced them with sine functions instead. This was a ratio, but rather the opposite of the angle in a right angle of fixed hypotenuse. A Muslim astronomer now compiled all of these ideas of both the Indians and the Greeks.

Now, in the 13th century, Germans made modern trigonometry by defining trigonometry functions as ratios rather than lengths of lines. Another Astronomer from Sweden discovered logarithms, and then another large step in Trigonometry was made by Isaac Newton whom founded differential and integral calculus. The history of Trigonometry came about mainly due to the purposes of time keeping and astronomy.

Four different careers that use trigonometry are Sailors, Astronomy, Architects, and Surveyors. Sailors use trigonometry for geography and...

The Reasons Capital Punishment Should Stay Implemented
“When someone commits a felony, it is a matter of free will. No one is compelled to commit armed robbery, murder, or rape. The average citizen does not have the mind or intentions to become a killer(Ornellas).” This statement by Lori Ornellas, a victim in the brutal murder of her nephew shows us that when someone commits a crime they do it on their own...

Pharmacokinetics
According to the Medical dictionary the definition of “Pharmacokinetics is, sometimes abbreviated as PK, the word coming from Ancient Greek pharmakon "drug" and kinetikos "to do with motion,” is a branch of pharmacology dedicated to the determination of the fate of substances administered externally to a living organism. The substances of interest include pharmaceutical agents, hormones, nutrients,...

...1. Calculus is split into two branches, differential calculus and integral calculus. Differential calculus is used to find the rates of change for geometric curves. This means that differential calculus is used to find the slope or tangent along a specific direction of a geometric curve. This relates directly to change, because finding the slope or tangent of a geometric curve is essentially finding the rate of change for...

...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 of...
