Question

Heyy guys plss help solve out these questions...​

Answer 1

Hello mate!!!

Here's the answer to your 1st question

a² + 4 = (tanθ − cotθ)² + 4

= tan²θ + cot²θ − 2 + 4

= (tan²θ + 1) + (cot²θ + 1)

= (sec²θ)(csc²θ)

b² − 1 = (cosθ − sinθ)² − 1

= cos²θ + sin²θ − 2sinθcosθ − 1

= −2sinθcosθ

(a² + 4)(b² − 1)²

= (sec²θ)(csc²θ) × (−2sinθcosθ)²

= 4.

The answer to your second question is in the attachment above...

Hope it helps!!!

Mark it as the brainliest one...
