\/ 4 - x
-----------
x
sqrt(4 - x^2)/x
Apply the quotient rule, which is:
and .
To find :
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.
Apply the power rule: goes to
So, the result is:
The result is:
The result of the chain rule is:
To find :
Apply the power rule: goes to
Now plug in to the quotient rule:
Now simplify:
