Derivative of 4*sin(6x)

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

   1. Let $u = 6 x$.

   2. The derivative of sine is cosine:

      $$\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$$

   3. Then, apply the chain rule. Multiply by $\frac{d}{d x} 6 x$:

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

         1. Apply the power rule: $x$ goes to $1$

         So, the result is: $6$

      The result of the chain rule is:

      $$6 \cos{\left(6 x \right)}$$

   So, the result is: $24 \cos{\left(6 x \right)}$

The answer is:

$$24 \cos{\left(6 x \right)}$$
