$$\sin{\left(90 \right)}$$

sin(90)

Detail solution

Let $u = 90$ .
The derivative of sine is cosine:

$\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} 90$ :
1. The derivative of the constant $90$ is zero.
The result of the chain rule is:

$0$

The answer is:

$0$
