integral of x-2sin(x)

integral

x - 2 sin (x)

\frac{x ^{2}}{2} + 2 cos (x) + C

Solution steps

\int x - 2 sin (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x d x - \int 2 sin (x) d x

\int x d x = \frac{x ^{2}}{2}

\int 2 sin (x) d x = - 2 cos (x)

= \frac{x ^{2}}{2} - (- 2 cos (x))

Simplify

= \frac{x ^{2}}{2} + 2 cos (x)

Add a constant to the solution

= \frac{x ^{2}}{2} + 2 cos (x) + C

\frac{x - 1}{( x + 1 ) ^{3}}

\frac{cos ^{2} ( t )}{2}

\frac{1}{( e ^{x} + e ^{- x} ) ^{2}}

\frac{x}{( x + 1 )}
