Question

Evalute cos^2theta tan^2theta + tan^2theta sin^2theta in terms of tan theta. ​

Answer 1

Hope it helps you plz mark as brilliant answer

Answer 2

Given :  Cos²θtan²θ + tan²θsin²θ

To Find : Evaluate in terms of tan theta. ​

Solution

Cos²θtan²θ + tan²θsin²θ

Taking tan²θ common

= tan²θ (Cos²θ + sin²θ )

Apply the formula that Cos²θ + sin²θ   = 1

= tan²θ (1 )

= tan²θ

Cos²θtan²θ + tan²θsin²θ  = tan²θ
