Question

prove that
sinA×secA+cosA×cosecA=secA×cosecA​

Answer 1

Answer:

$\large{\boxed{\green{\mathcal{Answer-}}}}$

$\sin(a) \times \sec(a) + \cos(a) \times \csc(a) = \sec(a) \times \csc(a)$

TAKING L.H.S.

$= \frac{ \sin(a) }{ \cos(a) } + \frac{ \cos(a) }{ \sin(a) } \\ = \frac{ { \sin(a) }^{2} + { \cos(a) }^{2} }{ \sin( a) \times \cos(a) } \\ = \frac{1}{ \sin(a) \times \cos(a) } \\ = \sec(a) \times \csc(a) \\ = rhs$
