integral of ((1-cos(x)))/x

integral

\frac{( 1 - cos ( x ) )}{x}

ln ∣ x ∣ - Ci (x) + C

Solution steps

\int \frac{1 - cos ( x )}{x} d x

Expand

\frac{1 - cos ( x )}{x} : \frac{1}{x} - \frac{cos ( x )}{x}

= \int \frac{1}{x} - \frac{cos ( x )}{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 \frac{1}{x} d x - \int \frac{cos ( x )}{x} d x

\int \frac{1}{x} d x = ln ∣ x ∣

\int \frac{cos ( x )}{x} d x = Ci (x)

= ln ∣ x ∣ - Ci (x)

Add a constant to the solution

= ln ∣ x ∣ - Ci (x) + C

(3 x - 4)^{3}

sin^{2} (3 x)

x^{2} + a^{2}

\frac{y ^{2}}{2}

arctan (\frac{1 - 1}{x})
