    Convert the sec, tan, and cot functions to their sine and cosine equivalents. Then simplify the resulting fraction. As is often the case it helps to remember that sin^2x + cos^2x = 1

Trig identites [ 1 Answers ]

I need help verifying these trig identites: cos(x)/(1-sin(x))=sec(x)+tan(x) 1+cos(x)=sin(x)=2csc(x) sin(x)+cos(x)/sin(x)-cos(x)-sin(x)/cos(x)=sec(x)*csc(x)

ay I came this question: expand and simplify: tan( pi/2 - y) I used the compound angle formula for tan(x-y), but don't know what do when I have tan( pi/2), since I take it to as being non-defined since its an asymptote, but the answer for the question comes as cot (y), can someone please...
