$$\frac{d}{d x} \left(5 \sin{\left(x \right)} - \cos{\left(x \right)}\right)$$
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 cosine is negative sine:

      So, the result is:

    The result is:


The answer is:

The graph
The first derivative [src]
5*cos(x) + sin(x)
$$\sin{\left(x \right)} + 5 \cos{\left(x \right)}$$
The second derivative [src]
-5*sin(x) + cos(x)
$$- 5 \sin{\left(x \right)} + \cos{\left(x \right)}$$
The third derivative [src]
-(5*cos(x) + sin(x))
$$- (\sin{\left(x \right)} + 5 \cos{\left(x \right)})$$
