Let .
The derivative of is itself.
Then, apply the chain rule. Multiply by :
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
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 of the chain rule is:
The result of the chain rule is:
Now simplify:
The answer is:
2 sin (3*x) 6*cos(3*x)*e *sin(3*x)
2 / 2 2 2 2 \ sin (3*x) 18*\cos (3*x) - sin (3*x) + 2*cos (3*x)*sin (3*x)/*e
2 / 2 2 2 2 \ sin (3*x) 108*\-2 - 3*sin (3*x) + 3*cos (3*x) + 2*cos (3*x)*sin (3*x)/*cos(3*x)*e *sin(3*x)
