Answer 1

Heya friend !!✌️

So we are given with a question about trignometry.

Before solving this we must know an identity

sec^2 - tan^2 = 1

Also , sec^2 = tan^2 + 1

And u should also know ,,,

a^3 - b^3 = ( a - b ) ( a^2 + ab + b^2 )

After knowing these we can easily prove it ,,,,,,, refere to the pic

Thanks !!! Pls mark my answer as brainliest......
