Im really struggling with these proving identities problems can somebody please show me how to do these? I'm only aloud to manipulate one side of the equation and it has to equal the other side of the equation at the end
Problem 1. (1tanx) = (cosxsinx)/cosx
Problem 2. (secx+tanx)/(cscxcotx)  (secxtanx)/(cscx+cotx) = 2(secx+cscx)

a. multipy the left side by cos/cos, you get
(cossin)/cos
b. on the left, get a common denominator
(csc^2ctn^2)
then combine both terms into one fraction. It reduces rapidaly. If you get stuck convert all terms to sin, cos)
