Hello, homeylova223!
What intervals are given?
Differentiate: .
We have: .
Assume
Multiply by
. . Therefore: .
Differentiatte: .
We have: .
And we have two equations to solve:
. .
. .
Find the critical numbers of the function. I have two(?).
1. x square root(4-x) (This is what I did)
square root(4-x)(1)+(x) ((4-x))/((2 square root(4-x))
square root(4-x)+((1x))/((2 square root 4-x))
I think I differentiated for it but how would I factor to find the critical numbers?
2. sin^2(x)+cos(x)
cos^2(x)-sin(x)
Here I have the same issue as my top problem
