Answer 2

Answer:

hlo buddy

Step-by-step explanation:

L.H.S. = (cos A–sin A+1)/(cos A+sin A–1)

Dividing Numerator and Denominator by sin A,

= (cos A–sin A+1)/sin A/(cos A+sin A–1)/sin A

= (cot A - 1 + cosec A)/(cot A+ 1 – cosec A)

= (cot A - cosec2A + cot2A + cosec A)/(cot A+ 1 – cosec A) (using cosec2A - cot2A = 1)

= [(cot A + cosec A) - (cosec2A - cot2A)]/(cot A+ 1 – cosec A)

= [(cot A + cosec A) - (cosec A + cot A)(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 = R.H.S.
