__TO PROVE ;-__

__Cosec A - 1 / cosec A + 1 = ( cos A ) / 1 + sin a__**⇒**

PROOF ;-

**⇒ Now, first let us go with Left hand side-**

__''Here we need to prove that L. H . S is equal to R. H. S''__

With the help of the given identity we need to prove it -

With the help of the given identity we need to prove it -

Cosec A + Cot A - { Cosec A + Cot A} { Cosec A - Cot A } / Cot A - Cosec A + 1

**⇒ Left Hand Side**

**⇒**

**Cosec A + Cot A { 1 - cosec A + cot A } / cot A - cosec A + 1**

⇒ Cosec A + Cot A {

**{ 1 - cosec A + cot A } / cot A - cosec A + 1 because it gets cancelled }**

**-------------------------------------------------------------------------------------------------------**

⇒ Right hand side

**⇒ 1 +cos A / Sin A [ given }**

**⇒ 1 sin A cos A / sin A**

**⇒cosec A + cot A**

Hence R.H.S and L.H.S are same. so hence proved
