Integral(sin(x)/3 + cos(x)/4, (x, 0, pi))

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{\sin{\left(x \right)}}{3}\, dx = \frac{\int \sin{\left(x \right)}\, dx}{3}$
  1. The integral of sine is negative cosine:
    
    $\int \sin{\left(x \right)}\, dx = - \cos{\left(x \right)}$
  So, the result is: $- \frac{\cos{\left(x \right)}}{3}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{\cos{\left(x \right)}}{4}\, dx = \frac{\int \cos{\left(x \right)}\, dx}{4}$
  1. The integral of cosine is sine:
    
    $\int \cos{\left(x \right)}\, dx = \sin{\left(x \right)}$
  So, the result is: $\frac{\sin{\left(x \right)}}{4}$
The result is: $\frac{\sin{\left(x \right)}}{4} - \frac{\cos{\left(x \right)}}{3}$
Add the constant of integration:

$\frac{\sin{\left(x \right)}}{4} - \frac{\cos{\left(x \right)}}{3}+ \mathrm{constant}$

The answer is:

$\frac{\sin{\left(x \right)}}{4} - \frac{\cos{\left(x \right)}}{3}+ \mathrm{constant}$

$$\int \left(\frac{\sin{\left(x \right)}}{3} + \frac{\cos{\left(x \right)}}{4}\right)\, dx = C + \frac{\sin{\left(x \right)}}{4} - \frac{\cos{\left(x \right)}}{3}$$
