Yes - I can verify for you that it is correct. Was that your question?

[1-cos(2x)+sin(2x)]/[1+cos(2x)+sin(2x)]=tan(x) can some one show me the steps

[1-cos(2x)+sin(2x)]/[1+cos(2x)+sin(2x)]=tan(x) in proving this this

Replace the sin(2x) with its identity 2sinxcosx, and the cos(2x) with its identity 1-2sin^2x, and then simplify.
