Question

Tan square theta into sin square theta​

Answer 1

Answer:

1

Step-by-step explanation:

Answer 2

Here i have used x instead of theta

To prove : tan²x - sin²x=tan²xsin²x

Proof:

LHS= tan²x - sinx

=sin²x/cos²x - sin²x

Taking L.C.M we get

LHS=(Sin²x-sin²x. cos²x) /cos²x

= sin²x (1 - cos²x) /cos²x

=tan²x. sin²x

(1-cos²x=sin²x)
