Question

Prove the identity: (tanxsinx/secx-1)=1+cosx

Answer 1

I got to the part where I have (1-cos^2x)/1-cosx

Answer 2

\[(Sinx/Cosx)/((1/Cosx)-1)=\]
\[(Sinx/Cosx)/((1-Cosx)/Cosx)=\]
\[(Sinx/Cosx)*Cosx/(1-Cosx)=\]
\[Sinx/(1-Cosx)=\]

Answer 3

your touching the right side again.... how did u get the -1?

Answer 4

I did not touch the right side at all so far.

Answer 5

That -1 is from secx-1

Answer 6
