secT(sec^2T-1/ctn^T)
secT(1/cos^2T-sin^2T/cos^2T)
secT(1-sin^2T)/cos^2T
secT(cos^2T)/cos^2T
secT
What is a simplified form of the expression (sec^3 theta) - (sec theta/cot^2 theta)?
a. 0
b. sec theta-tan theta
c. cos theta
d. sec theta*****
Every time I attempt to work out this problem I end up with one. I know the answer is sec theta, but I do not know how to get there. Can someone show me how to get to this?
