Question

rationalise this plss

Answer 1

so here your answer is SecA +TanA

Answer 2

Hey

Here is your answer,

Sol:
√1+sin A / 1-sin A

= √(1+sin A) / (1-sin A ) x √(1+sin A) / (1+sin A )
= √(1+sin A)2 / (1-sin2 A )
= √(1+sin A)2 / cos2 A
= (1+sin A) / cos A
= (1/cos A + sin A/cos A)
= sec A + tan A.

√1+sin A / 1-sin A = sec A + tan A.

Hope it helps you!
