2.4 notes...ya its kinda like that sierra mist

Hey peeps...

Section 2.4 Notes!!!

Values of the Six Trigonometric Functions

The six trig funcions are :

1. Sine = Opposite/Hypotenuse
2. Cosine = Adjacent/Hypotenuse
3. Tangent = Oppoiste/Adjacent
4. Cosecant = Hypotenuse/Opposite
5. Secant = Hypotenuse/Adjacent
6. Cotangent = Adjacent/Opposite

**Note**

I tend to look at these functions in pairs. Sine and Cosecant are reflections of each other, Cosine and Secant are reciprocals of each other, and Tangent and Cotangent are reflections of each other.

**End Note**

All of the Trig functions for 180 degrees:

1. Sin = 0
2. Cos = -1
3. Tan = 0
4. Csc = undefined
5. Sec = -1
6. Cot = undefined

Find all the trigometric functions for theta in the triangle picture below

1. Sin = 5/10
2. Cos = 8/10
3. Tan = 5/8
4. Csc = 10/5
5. Sec = 10/8
6. Cot = 8/5

Find the trigmatic functions of the point (8,-5)

1. Sin = -5/(rad 89)
2. Cos = 8/(rad 89)
3. Tan = -5/8
4. Csc = (rad 89)/-5
5. Sec = (rad 89)/8
6. Cot = 8/-5

**Note**

I am really srry it says "rad 89" instead of having a radical sign. Copy and paste doesn't work and I don't use word I use word perfect so the add on wont work. If anyone could tell me how I could put in the actual symobol for rad I would greatly appreciate it. Thnanks!!!

**End Note**

EXAMPLE PROBLEM

Find all six trigmatic functions for the angle inbetween the sides with lengths 10 and 20

Answers with work!!!

1. Sin (opposite/hypotenuse) = 15/20 =3/4
2. Cos (adjacent/hypotenuse) = 10/20 = 1/2
3. Tan (opposite/adjacent) = 15/10 = 3/2
4. Csc ( hypotenuse/opposite) = 20/15 = 4/3
5. Sec (hypotenuse/adjacent) = 20/10 = 2
6. Cot (adjacent/opposite) = 10/15 = 2/3

REMINDER TOO MADI!!! CUZ UR THE LUCKY PERSON WHO GETS TO FOLLOW ME!!!!

Ok now its my personalization...I have thought really long and hard about this and I've decided there is only one thing to go with a chuck norris joke...cuz hes just that kool.

"Chuck Norris appeared in the "Street Fighter II" video game, but was removed by Beta Testers because every button caused him to do a roundhouse kick. When asked bout this "glitch," Norris replied, "That's no glitch.""
