Question

What is the antiderivative of `5+cosx`?

Answer 1

5x + sinx + C

Explanation:

Split into two integrals; `int__5dx` + `int__cos(x)dx`
Solve seperately; 5x, sin(x)
Add together; 5x + sin(x)
Add C (it's just a placeholder for a constant) as when you differentiate you may be losing a constant; 5x + sin(x) + C
