Prove:
(tanx + secx 1)/(tanx  secx + 1)= tanx + secx
My work so far:
(sinx/cosx + 1/cosx + cosx/cosx)/(sinx/cos x  1/cosx + cosx/cosx)= tanx + cosx
(just working on the left side)
((sinx + 1  cosx)/cosx)/((sinx  1 + cosx)/cosx)
((sinx + 1  cosx)/cos x) x (cos x/(sinx  1 + cosx))
(sinx + 1  cosx)/(sinx  1 + cosx)
here is where I get stuck. Could someone point me in the right direction?

Prove: sinx + tanx = tanx (1 + cosx) What I have so far: LS: = sinx + tanx = sinx + (sinx / cosx) = (sinx) (cosx) + sinx / cos = tanx (cosx + sinx) I don't know what to do now

Prove: (tanx)(sinx) / (tanx) + (sinx) = (tanx)  (sinx) / (tanx)(sinx) What I have so far: L.S. = (sinx / cosx) sinx / (sinx / cosx) + sinx = (sin^2x / cosx) / (sinx + (sinx) (cosx) / cosx) = (sin^2x / cosx) / (cosx / sinx + sinxcosx)
