Question

hello friends plz help me...hurry up​

Answer 1

Answer:

LHS, sin-cos+1/sin+cos-1

divide by cos

sin/cos -cos/cos +1/cos / sin/cos +cos/cos -1/cos

tan-1+sec/tan+1-sec

tan-1+sec/tan-sec+(sec²-tan²)                           (sec²=1+tan²)

tan-1+sec/tan-sec+(sec+tan)(sec-tan)               (a²-b²=(a+b)(a-b))

tan-1+sec/(sec-tan)(-1+sec+tan)

1/sec-tan=RHS

PROVED!!!:)
