Question

prove that tan squared theta minus secant squared theta is equals to minus one​

Answer 1

Answer:

Step-by-step explanation:

We know the identity, 1 + Tan²α = Sec²α

1 + Tan²α = Sec²α

=> 1 + Tan²α - Sec²α  = 0

=> Tan²α - Sec²α = - 1

Hence proved.

Answer 2

Answer:

the value of sec2-tan2

=1

(we get 1 as answer by the trigonometric Identeties )
