Exact Trig Values for 0 degrees, 30 degrees, etc

[Kriten-Sarah]

Two things that I'm having problems with are these

1) Convert each degree measure to radians. Give answers to the nearest hundredth of a radian. As an example see below.

112o, 252.5o, 210o35’

2) Convert each radian measure to degrees. Give answers to nearest tenth of a degree for examples look below

1.8, 3.5, 2.41

I have no idea how to do this or what formula to use

3) Fill in the following chart with the exact values. I also am not so sure about this I can find the decimals for these such as sin 30 degrees equals 0.5 but not sure how to get the exact trig value

Angle Sin q Cos q Tan q Csc q Sec q Cot q
0o ____ ____ ____ ____ ____ ____
30o ____ ____ ____ ____ ____ ____
45o ____ ____ ____ ____ ____ ____
60o ____ ____ ____ ____ ____ ____
90o

I'm not sure how to find exact trig values. please help

1) Use the fact that 180 degrees equals 1 pi radian. Note: One "minute" is 1/60 of a degree.

2) Use the fact that 1 pi radian equals 180 degrees.

3) These are values that you were supposed to have memorized. Go back in your book and/or your class notes, find the table where they gave you these values (at least for sine, cosine, and tangent), and memorize the values. You will need them!
