4 6*sin (x)
d / 4 \ --\6*sin (x)/ dx
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of sine is cosine:
The result of the chain rule is:
So, the result is:
The answer is:
3 24*sin (x)*cos(x)
2 / 2 2 \ -24*sin (x)*\sin (x) - 3*cos (x)/
/ 2 2 \ -48*\- 3*cos (x) + 5*sin (x)/*cos(x)*sin(x)
