Question

va rog mult URGENT....​

Answer 1

Explicație pas cu pas:

$\int \dfrac{1 - \cos \ x}{2} \ dx = \int \Big(\dfrac{1}{2} - \dfrac{\cos \ x}{2}\Big) \ dx =$

$= \int \dfrac{1}{2} \ dx - \dfrac{\cos \ x}{2} \ dx = \dfrac{1}{2}\int \ 1 \ dx - \dfrac{1}{2} \int \cos \ x \ dx$

$= \dfrac{x}{2} - \dfrac{\sin \ x}{2} + C = \dfrac{x - \sin \ x}{2} + C$
