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 :
Differentiate term by term:
The derivative of the constant is zero.
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:
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 (1 - 3*x) -6*cos(-1 + 3*x)*e *sin(1 - 3*x)
2 / 2 2 2 2 \ sin (-1 + 3*x) 18*\cos (-1 + 3*x) - sin (-1 + 3*x) + 2*cos (-1 + 3*x)*sin (-1 + 3*x)/*e
2 / 2 2 2 2 \ sin (-1 + 3*x) 108*\-2 - 3*sin (-1 + 3*x) + 3*cos (-1 + 3*x) + 2*cos (-1 + 3*x)*sin (-1 + 3*x)/*cos(-1 + 3*x)*e *sin(-1 + 3*x)
