Question

d/dx [(sin(pi/2) + cos(pi/2)]^5

Answer 1

\[\Large\rm \left[\sin(\pi/2)+\cos(\pi/2)\right]^5=\text{#}\]\[\Large\rm \frac{d}{dx}\text{#}=0\]

Answer 2

There is no x variable present.
Did you want to take derivative and then evaluate it at x=pi/2 instead maybe?

Answer 3

so its 0 ?

Answer 4

Yes c:
There is no x variable, the entire thing is constant with respect to x.
Derivative, or rate change, of a constant is zero.

Answer 5

thanks!
