integral from-1 to 0 of 1/(1+cos(x))

\int_{- 1}^{0} \frac{1}{1 + cos ( x )} d x

tan (\frac{1}{2})

Decimal Notation

0.54630 \dots

Solution steps

\int_{- 1}^{0} \frac{1}{1 + cos ( x )} d x

Apply u-substitution

: \int_{- t a n (\frac{1}{2})}^{0} 1 d u

= \int_{- t a n (\frac{1}{2})}^{0} 1 d u

Integral of a constant:

\int a d x = a x

= [1 \cdot u]_{- t a n (\frac{1}{2})}^{0}

Simplify

= [u]_{- t a n (\frac{1}{2})}^{0}

Compute the boundaries:

tan (\frac{1}{2})

= tan (\frac{1}{2})

\int_{0}^{π} sin (x) \cdot cos (n x) d x

\int_{- 1}^{4} x^{2} - 3 x - 4 d x

\int_{\frac{1}{2}}^{\frac{3}{2}} (x^{2} + x + 1) d x

\int_{0}^{1} - x d x

\int_{0}^{2} 9 x^{2} x^{3} + 1 d x
