Question

simplify sin^2 x/1-cos x

Answer 1

You mean:
\[\frac{ \sin ^{2}(x) }{ 1-\cos(x)}\]?

Answer 2

yes

Answer 3

sin^2x =1- cos^x= (1-cosx) (1+cosx)
1-cos x will vanish

Answer 4

Yeah, exactly (fast typer)

Answer 5

\[= \frac{ (1+\cos(x))(1-\cos(x)) }{ 1-\cos(x) }\]

Answer 6

yupp thank you
