5 2*sin (x)
d / 5 \ --\2*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:
4 10*sin (x)*cos(x)
3 / 2 2 \ -10*sin (x)*\sin (x) - 4*cos (x)/
2 / 2 2 \ -10*sin (x)*\- 12*cos (x) + 13*sin (x)/*cos(x)
