Detail solution
  1. Differentiate term by term:

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

      1. The derivative of sine is cosine:

      So, the result is:

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

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

        1. The derivative of cosine is negative sine:

        So, the result is:

      So, the result is:

    The result is:


The answer is:

The graph
The first derivative [src]
3*cos(x) + 4*sin(x)
$$4 \sin{\left(x \right)} + 3 \cos{\left(x \right)}$$
The second derivative [src]
-3*sin(x) + 4*cos(x)
$$- 3 \sin{\left(x \right)} + 4 \cos{\left(x \right)}$$
The third derivative [src]
-(3*cos(x) + 4*sin(x))
$$- (4 \sin{\left(x \right)} + 3 \cos{\left(x \right)})$$
