integral from 0 to 0.5 of tan(x)

\int_{0}^{0.5} tan (x) d x

0.13058 \dots

Solution steps

\int_{0}^{0.5} tan (x) d x

Rewrite using trig identities

= \int_{0}^{0.5} \frac{sin ( x )}{cos ( x )} d x

Apply u-substitution

= \int_{1}^{0.87758 \dots} - \frac{1}{u} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{0.87758 \dots}^{1} - \frac{1}{u} d u

Take the constant out:

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

= - (- \int_{0.87758 \dots}^{1} \frac{1}{u} d u)

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= - (- [ln ∣ u ∣]_{0.87758 \dots}^{1})

Simplify

= [ln ∣ u ∣]_{0.87758 \dots}^{1}

Compute the boundaries:

0.13058 \dots

= 0.13058 \dots
