Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
2 x 1 - -------- 2 -25 + x ------------- __________ / 2 \/ -25 + x
/ 2 \ | x | 3*x*|-1 + --------| | 2| \ -25 + x / ------------------- 3/2 / 2\ \-25 + x /
