/ 4 \ log(x) \2*x - 3*sin(x)/*------ log(2)
(2*x^4 - 3*sin(x))*(log(x)/log(2))
Apply the quotient rule, which is:
and .
To find :
Apply the product rule:
; to find :
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of sine is cosine:
So, 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:
; to find :
The derivative of is .
The result is:
To find :
The derivative of the constant is zero.
Now plug in to the quotient rule:
Now simplify:
The answer is:
