Rewrite csc 56.5 degree, in terms of its cofunction. csc 56.5 degree = degree (Type an exact answer. Simplify your answer.

Solution

he value of a trig function of an angle equals the value of the cofunction of the complement of the angle.

Since co-function of cscx :

cosx = sec(90 -x)

So,csc56.5 =sec(90 -56.5)

= sec33.5
