Question

Simplify this equation please

Answer 1

Answer:

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

Step-by-step explanation:

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

$\dfrac{1}{\tan^2 \theta} \sin^2\theta+\cos^2\theta$

$\dfrac{1}{\dfrac{\sin^2\theta}{\cos^2\theta} } \sin^2\theta+\cos^2\theta$

$\dfrac{\cos^2\theta}{\sin^2\theta } \sin^2\theta+\cos^2\theta$

$\cos^2\theta+\cos^2\theta$

$2\cos^2\theta$
