Answer 1

Step-by-step explanation:

=sin A/ 1 - cos A

=sin A(1+cos A) / 1-cos²A

=sin A(1+cosA) / sin² A

=(1+cos A ) / sin A

=cosec A + cot A.

Answer 2

Answer:

sinA/1-cosA,

Multiply numerator and denominator by (1+cosA),

LHS=sinA(1+cosA) /(1-cosA) (1+cosA)

=sinA(1+cosA)/(1-cos^2A)

=sinA(1+cosA)/sin^2A [Since,sin^2A+cos^2A=1]

=(1+cosA)/sinA

=1/sinA+cosA/sinA

=cosecA+cotA=RHS

Therefore,LHS=RHS

Hence Proved.
