Question 964860: (1). Simplify the trigonometric expression to a multiple or power of a single trig function.
cot(-α)cos(-α) +sin(-α) =
(2). Change all trigonometric functions in the expression to sines and cosines and simplify.

(cos(−x))/(sec x + tan(−x))
Thank you

(1). Simplify the trigonometric expression to a multiple or power of a single trig function.
cot(-α)cos(-α) +sin(-α) =
use x in place of α
cot%28-x%29cos%28-x%29%2Bsin%28-x%29
%28cos%28-x%29%2Fsin%28-x%29%29%2Acos%28-x%29%2Bsin%28-x%29
%28cos%5E2%28-x%29%2Bsin%5E2%28-x%29%29%2Fsin%28-x%29=1%2Fsin%28-x%29=csc%28-x%29
(2). Change all trigonometric functions in the expression to sines and cosines and simplify.
(cos(−x))/(sec x + tan(−x))
%28cos%28-x%29%29%2F%28sec%28x%29%29+%2B+tan%28-x%29
%28cos%28-x%29%29%2F%281%2Fcos%28x%29%29+%2B%28sin%28-x%29%2Fcos%28-x%29%29
cos(x)=cos(-x)
cos%5E2%28-x%29+%2B%28sin%28-x%29%2Fcos%28-x%29%29
