After you have finished constructing the spaghetti sine curve, answer the following questions.

What is the radius of the circle? 5in

What is the circumference of the circle? 2πr=2(π)(5)=31.4

At what degree measure on your circle would you find the angle correponding to 375°? 15 degrees What is the term for the angle you found in question #3? reference angle

After how many degrees does the graph start to repeat? 360 degrees This is the period of the graph and corresponds to one complete wave – a wavelength.

What is the height of the triangle (spaghetti) at 30 degrees? Compare this to the radius (that it, find the ratio: [pic]and make it a decimal). 2.5/5=.5 On the calculator find the sine of 30º: .5 How does that compare to your answer above for [pic]?

it is the same
What is the height of the triangle at 150° and 330°? 2in. How does this compare with the height of the 30° angle in #6 above? it is the same.

What is the height of the triangle at 45°, 135°, 225°? 3.5in. Make a ratio of for these angles like you did in #6: 3.5/5=.7 On the calculator find the sine of 45°: .707 Compare this to your answer to question #9.

this is very close
If you were to explain to a person who has never seen trigonometry what the sine of an angle is, what would you tell them?

I would tell them that it is the side opposite of the angle over the hypotenuse which is the radius of the circle.

12. What do you think is the significance of reference angles?
If you know the main reference angles than you can use that information to find other angles on the circle. -----------------------
Name_______________________________Per._____

Draw the x and y axis on your circle.
With a protractor put a mark every 15° and extend these marks from the origin to the edge of the circle. Take a string and wrap it carefully around the circumference of your circle. Put a mark on the string at all of your 15° intervals. Take the string and...

Flying Spaghetti MonsterAnalysis
As soon as one begins to read The Essay on The Flying Spaghetti Monster, they can infer that it is a paradoy. The essay uses the technique of puns with the name of “Pastafarians”, and exaggeration with the Global Warming Graph, but the main technique used was sarcasm.The entire essay was a sarcastic attempt to show that Intellegent Design...

Introduction
The aim of this experiment will be to conduct an investigation into a factor of spaghetti. Such factors include how the diameter will relate to the flexibility of the spaghetti, or how the carbohydrate content will relate to the flexibility. For this experiment, the carbohydrate content and how it relates to the flexibility will be investigated.
Flexibility will...

Modeling Data With Trigonometric Functions
Precalculus 1113-213
October 18, 2011
Real-life math is used in many activities that people do in a daily basis. In the next few paragraphs I will be explaining how to use a real world data and model it with a sine function of the form of y= a sin K (x-b). The graphs will use the law of sine which is defines as, “a law stating that the ratio of the sine of an arc of a spherical triangle to the sine of the opposite angle is the...

...Happiness, and Spaghetti Sauce was a well thought-out brain teaser type of video. Author and writer Malcom Gladwell introduces the audience to the food industry’s pursuit of the perfect spaghetti sauce, but ends up making a larger argument about the nature of choice and happiness in a comical yet intelligent manor on TEDTalk. Gladwell uses his friend and Psychophysicist Howard Moskowitz’s crazy idea with Pepsi, and breakthrough formula for success with Vlasic...

...π2) includes all possible values. The range still remains all real numbers. Exchanging the domain and range gives us all real numbers as the domain and (-π2, π2) as the range.
As you can see, the properties of the six trig functions have many similarities and the inverse trig functions’ domain and range can be obtained with the one to one property of inverse functions...
