Answer:

We have,

√SecA-tan A/SecA+tana=√SecA-tanA/√SecA+tanA×√SecA-tanA/SecA-tanA

=(SecA-tanA) /(Sec^2A-tan^2A) =(SecA-tanA) ------- equation 1 And

√cosec A- cotA /cosec A+cot A=√cosec A - cot A /√cosec A +cot A×√√cosec A-cotA/√cosec A-cotA

=(cosec A- cot A) /√(cosec^2-cot^2A) ----- equation 2

[cosec ^2A - cot ^2=1]

From equation 1 and 2 we get.

=(1-sinA ) (1-cos A) /cos A sin A=(1-cosA) /cosA . (1-sinA) /sinA

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

=(secA-1) (cosec A -1) =RHS.

Therefore, LHS=RHS.
