Problem 2. (secx+tanx)/(cscx-cotx) - (secx-tanx)/(cscx+cotx) = 2(secx+cscx)

**bobpursley**, Thursday, November 1, 2012 at 9:49pma. multipy the left side by cos/cos, you get

(cos-sin)/cos

b. on the left, get a common denominator

(csc^2-ctn^2)

then combine both terms into one fraction. It reduces rapidaly. If you get stuck convert all terms to sin, cos)
