Suppose that (theta) is an angle in standard position whose terminal side intersects the unit circle at (3/5, 4/5). find the exact value of cos(theta) csc(theta) and tan(theta)

Answer 1

Start from the definitions:

cos(theta) = (length of adjacent side)/(length of hypotenuse) = length of adjacent side (since hypotenuse is 1).

Thus, cos(theta) = 3/5. Can you do the others from here?
