Question

(1-cos square theta )sec square theta =tan square theta​

Answer 1

(1-cos²theta)sec²theta

sin²theta×1/cos²theta

sin²theta/cos²theta

tan²theta

Answer 2

Answer:

1-cos^2 theta = sin^2 theta,

sec^2 theta = 1/cos^2 theta

sin^2 theta / cos^2 theta = tan^2 theta,

LHS= RHS..

hence proved..

hope it is helpful..
