tan(x) ___ 2 + \/ x *sin(2*x)
2^tan(x) + sqrt(x)*sin(2*x)
Differentiate term by term:
Let .
Then, apply the chain rule. Multiply by :
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:
The result of the chain rule is:
Apply the product rule:
; to find :
Apply the power rule: goes to
; to find :
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
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 of the chain rule is:
The result is:
The result is:
Now simplify:
The answer is:
sin(2*x) ___ tan(x) / 2 \ -------- + 2*\/ x *cos(2*x) + 2 *\1 + tan (x)/*log(2) ___ 2*\/ x
