Answer:

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

Step-by-step explanation:

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

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

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

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

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

$2\cos^2\theta$

What is the value of this expression when c= -4 and d = 10?

Alisiya [41]

Answer:

$c + d^2 = 96$

Step-by-step explanation:

Given

$c = -4\\d = 10$

Required

Find $c + d^2$

To find $c + d^2$ , we simply substitute 10 for d and -4 for c in the given expression.

The step is as follows:

$c + d^2$

Substitute $c = -4\\d = 10$

$c + d^2 = -4 + 10^2$

$c + d^2 = -4 + 10*10$

$c + d^2 = -4 + 100$

$c + d^2 = 96$

The expression cannot be solved any further; so, we can conclude that when d = 10 and c = -4, $c + d^2 = 96$
