2*sin(2*x) + 3 + 3*cos(4*x)
d --(2*sin(2*x) + 3 + 3*cos(4*x)) dx
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
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:
So, the result is:
The derivative of the constant is zero.
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 is:
The answer is:
-12*sin(4*x) + 4*cos(2*x)
-8*(6*cos(4*x) + sin(2*x))
16*(-cos(2*x) + 12*sin(4*x))
16*(-cos(2*x) + 12*sin(4*x))
