Use the given value and the trigonometric identities to find the remaining trigonometric functions of the angle. sec(θ) = − 3/2 cot(θ) > 0 sin(θ) = cos(θ) = tan(θ)...

if sin theta= 0.4, what is the exact value of sin theta+ cos(pi/2-theta)

I am not very sure how to go about this or start to answer it.

Help please

cscΦ = 2.3 How would I find theta in degrees using my graphing calculator. Would I just use sin on both sides to cancel out theta or would I have to do something else?
