Use the info given to evaluate the cosecant trig function, if possible.
cos(pi/2  x) = 3/5, cos x = 4/5
Is this 5/3? I don't get the question completely.

Best ResponseYou've already chosen the best response.0\(cos (\pi/2  x) = sin x\) → that's a cofunction identity so they want the cosecant of the angle whose sine is 3/5 and cosine is 4/5

Best ResponseYou've already chosen the best response.1Oh, ok. I forgot the cofunction identity part. I just drew a triangle with the cos = 4/5 part.

Best ResponseYou've already chosen the best response.0that's usually how I do it. and then just use the second given trig function to make sure the sign is correct
