Question

Prove the above trigonometric identities..​

Answer 1

Answer:

cos²A/1-sinA/cosA +sin³A/sinA-CosA

cos³A/cosA - sinA+sin³A/sinA-cosA

cos³A/cosA-sinA -sin³A/cosA-sinA

1/cosA-sinA(cos³A-sin³A)

1/cosA-sinA{(cosA-sinA) (cos²A+sin²A+cosAsinA)

1+sinAcosA

Answer 2

COS3A/COSA-SINA +SIN3A/SINA-COSA

-COS3A/SINA-COSA + SIN3A/SINA-COSA

SIN3A-COS3A/SINA-COSA

(SINA-COSA)(SIN2A+COS2A+SINA.COSA)/SINA-COSA

1+SINA.COSA .
