I need help with verifying Trig. Identities
[ 0 Answers ]
Can somebody show me step-by-step instructions on verifying these two Trig. Identities. 1. (1+sinx)/(1-sinx)=(secx+tanx)^2 2.(1-2cos^2x)/(sinxcosx)=tanx-cotx The homework is due tomorrow afternoon. Thanks!

I solved the first one I posted but the second one still gets me I can get to 2sin(X)cos(X)-(sin(X))/(cos(X))=(sin(X))/(cos(X))cos(2X) but I don't know which identity to use for cos(2X) in the left side. the original identity is sin(2X)-tan(X)=tan(X)cos(2X)
