sin(5*x) - ------
log(x)
sin(5*x) - 1/log(x)
Differentiate term by term:
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 derivative of a constant times a function is the constant times the derivative of the function.
