Question

hi friends...gm

solve 29

Answer 1

ANSWER:

$l.h.h \\ = \sqrt{ \frac{1 - cos \alpha }{1 + cos \alpha } } \\ = \sqrt{ \frac{(1 - cos \alpha )(1 + cos \alpha )}{ {(1 + cos \alpha )}^{2} } } \\ = \sqrt{1 - {cos} ^{2} \alpha } \times \frac{1}{1 + cos \alpha } \\ = sin \alpha \times \frac{1}{1 + cos \alpha } \\ = \frac{sin \alpha }{1 + cos \alpha } \\ = r.h.s$

HERE ,

IM TAKING ALPHA AS 'A'

HOPE IT HELPED YOU
