Let .
The derivative of is itself.
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
The derivative of cosine is negative sine:
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:
So, the result is:
The result of the chain rule is:
The answer is:
-cos(5*x) 5*e *sin(5*x)
/ 2 \ -cos(5*x) 25*\sin (5*x) + cos(5*x)/*e
/ 2 \ -cos(5*x) 125*\-1 + sin (5*x) + 3*cos(5*x)/*e *sin(5*x)
