Detail solution

Differentiate $- 4 \sin{\left(x \right)} + 3 \cos{\left(x \right)}$ 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 cosine is negative sine:
    
    $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
  So, the result is: $- 3 \sin{\left(x \right)}$
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 sine is cosine:
      
      $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
    So, the result is: $4 \cos{\left(x \right)}$
  So, the result is: $- 4 \cos{\left(x \right)}$
The result is: $- 3 \sin{\left(x \right)} - 4 \cos{\left(x \right)}$

The answer is:

$- 3 \sin{\left(x \right)} - 4 \cos{\left(x \right)}$

The first derivative [src]

-4*cos(x) - 3*sin(x)

$$- 3 \sin{\left(x \right)} - 4 \cos{\left(x \right)}$$
