d / / 2\\ --\sin(4*x) + cos\3*x // dx
Differentiate term by term:
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:
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:
The result is:
The answer is:
/ 2\ 4*cos(4*x) - 6*x*sin\3*x /
/ / 2\ 2 / 2\\ -2*\3*sin\3*x / + 8*sin(4*x) + 18*x *cos\3*x //
/ / 2\ 3 / 2\\ 4*\-16*cos(4*x) - 27*x*cos\3*x / + 54*x *sin\3*x //
