Question

sin theta /1+cos theta is​

Answer 1

To prove :

$\frac{sinx}{1 + cosx}$

Proof :

$\frac{sinx}{1 + cosx} \times \frac{1 - cosx}{1 - cosx}$

$\frac{sinx.sinxcosx}{1 - cos {}^{2}x }$

$sinx( \frac{1 - cosx}{sin {}^{2} x} )$

$\frac{1 - cosx}{sinx}$

$cosecx - \: cotx$

Hope this helps u

#Instead of theta I replaced by "X"
