___________ / 2 \/ 25 - 9*x
/ ___________\ d | / 2 | --\\/ 25 - 9*x / dx
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Differentiate term by term:
The derivative of the constant is zero.
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
So, the result is:
The result is:
The result of the chain rule is:
Now simplify:
