Question

Simplify this equation please

Answer 1

`\boxed{2\cos^2\theta}`

Explanation:

`\cot^2\theta \sin^2\theta+\cos^2\theta`

`(1)/(\tan^2 \theta) \sin^2\theta+\cos^2\theta`

`(1)/((\sin^2\theta)/(\cos^2\theta) ) \sin^2\theta+\cos^2\theta`

`(\cos^2\theta)/(\sin^2\theta ) \sin^2\theta+\cos^2\theta`

`\cos^2\theta+\cos^2\theta`

`2\cos^2\theta`
