Question 866193: prove the identity
1- cos2x/1+sinx = sinx
what I have so far:
=1-(1-sin^2x/1+sinx)
= 1-(sin^2x/sinx)
=1-sinx
how do I get rid of that one?
thanks!

prove the identity
1- cos2x/1+sinx = sinx
what I have so far:
=1-(1-sin^2x/1+sinx) *** --> 1 - (1 - sin) --> sin = sin
===========================================================
= 1-(sin^2x/sinx)
=1-sinx
how do I get rid of that one?
