/ ___ ___\ 2*\tan(x)*\/ x - \/ x /
2*(tan(x)*sqrt(x) - sqrt(x))
The derivative of a constant times a function is the constant times the derivative of the function.
Differentiate term by term:
Apply the product rule:
; to find :
Rewrite the function to be differentiated:
Apply the quotient rule, which is:
and .
To find :
The derivative of sine is cosine:
To find :
The derivative of cosine is negative sine:
Now plug in to the quotient rule:
; to find :
Apply the power rule: goes to
The result is:
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:
So, the result is:
Now simplify:
The answer is:
