Let .
Then, apply the chain rule. Multiply by :
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
Differentiate term by term:
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 derivative of the constant is zero.
The result is:
The result of the chain rule is:
The result of the chain rule is:
Now simplify:
The answer is:
sin(a*x + b) a*c *cos(a*x + b)*log(c)
2 sin(b + a*x) / 2 \ a *c *\-sin(b + a*x) + cos (b + a*x)*log(c)/*log(c)
3 sin(b + a*x) / 2 2 \ a *c *\-1 + cos (b + a*x)*log (c) - 3*log(c)*sin(b + a*x)/*cos(b + a*x)*log(c)
