Best ResponseYou've already chosen the best response.0cosx  + sec x tanx cosx 1  +  sinx sinx  cos x cosx divided by sinx/cosx is actually cosx times cosx/sinx cos^2x 1  +  sinx sinx cos^2x + 1  sinx That may be as far as you can take it...

Best ResponseYou've already chosen the best response.0The last step blex did is wrong. cos^2 is not equal to cos^2+1. Cos/Tan + Sec Cos^2/Sin + Sec... Expanding the tangent into its components. (Sin^2  1)/Sin + Sec... Using the identity sin^2 + cos^2 = 1. Sin^2/Sin  1/Sin + Sec... Separating out the numerator of the fraction. Sin  Sec + Sec... The first term has a sin that cancels, the second term is just secant. Sin... Both the secants cancel and you're left with just sin.
