Question

(cosec A - sin A)(sec A - cos A) equal to 1 by tanA palash cot A

Answer 1

answer: LHS=

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

(1-sinsquareA/sinA)(1-cossquareA/cosA)

cossquareA/sinA)(sinsquareA/cosA)

cosA.sinA

RHS=

1/sinA/cosA + cosA/sinA

1/sinsquareA+cossquareA/cosA.sinA

1/1cosA.sinA

cosA.sinA

THEREFORE LHS=RHS
