Answer:

Explanation:

sin²β + sin²β×tan²β = tan²β

sin²β( 1 + tan²β ) = tan²β

~~~~~~~~~~~~~~~~

sin²β + cos²β = 1


(sin^2\beta )/(cos^2\beta ) +
(cos^2\beta )/(cos^2\beta ) =
(1)/(cos^2\beta ) ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β

~~~~~~~~~~~~~~

1 + tan²β =
(1)/(cos^2 \beta )

L.H. = sin²β (
(1)/(cos^2 \beta ) ) = tan²β

R.H. = tan²β
