Question

How would I determine the value of the trig ratios when I'm given the angle in radians for example `csc 3.3`?

Answer 1

Find the trig ratios of csc 3.3. (3.3 in radians)

Explanation:

First, convert 3.3 radians to deg:
pi = 3.14 --> 180 deg
3.3 --> 180(3.3/3.14) = 189.17 deg (Quadrant III)

Calculator gives -> sin 189.17 = -0.159
cos (189.17) = -0.99
tan (189.17) = 0.16
cot (189.17) = 1/0.16 = 6.19
sec (189.17) = 1/cos = 1/-0.99 = -1.01
csc (189.17) = 1/sin = 1/-0.159 = -6.29
