v

The graph:

from to

Piecewise:

The solution

You have entered [src]
sin(8*x)
$$\sin{\left(8 x \right)}$$
sin(8*x)
Detail solution
  1. Let .

  2. The derivative of sine is cosine:

  3. Then, apply the chain rule. Multiply by :

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: goes to

      So, the result is:

    The result of the chain rule is:


The answer is:

The graph
The first derivative [src]
8*cos(8*x)
$$8 \cos{\left(8 x \right)}$$
The second derivative [src]
-64*sin(8*x)
$$- 64 \sin{\left(8 x \right)}$$
The third derivative [src]
-512*cos(8*x)
$$- 512 \cos{\left(8 x \right)}$$
