integral from 0 to 1 of cos(wx)

\int_{0}^{1} cos (w x) d x

\frac{sin ( w )}{w}

Solution steps

\int_{0}^{1} cos (w x) d x

Apply u-substitution

: \int_{0}^{w} \frac{cos ( u )}{w} d u

= \int_{0}^{w} \frac{cos ( u )}{w} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{w} \cdot \int_{0}^{w} cos (u) d u

Use the common integral:

\int cos (u) d u = sin (u)

= \frac{1}{w} [sin (u)]_{0}^{w}

Compute the boundaries:

sin (w)

= \frac{1}{w} sin (w)

Simplify

= \frac{sin ( w )}{w}

\int_{- 1}^{5} 2 x + 6 - x + 1 d x

\int_{- 2}^{3} (9 - x^{2}) - (3 - x) d x

\int_{0}^{x^{3}} e^{- 2 t} d t

\int_{3}^{7} x^{2} lo g_{10} (x) d x

\int_{6}^{9} (\frac{1}{x ^{2}}) d x
