Question

(sec^2theta-1)cot^2theta=1​

Answer 1

hey mate

proof here

(sec ^2 x -1) cot^2x=1.

but we know,

sec^2 x - tan ^2 x =1.

so,

sec^2 x- 1= tan^2 x .

take L.H.S.

=(sec ^2 x -1) cot^2x

= tan ^2 x * cot ^2 x.

= tan^2 x. * 1/tan^2 x

= 1.

=R.H.S.

hence proved .

i hopes its helps u.

please follow me!!✌✌
