integral from 0 to 2 of 1/((1+x)^2)

\int_{0}^{2} \frac{1}{( 1 + x ) ^{2}} d x

\frac{2}{3}

Decimal

0.66666 \dots

Solution steps

\int_{0}^{2} \frac{1}{( 1 + x ) ^{2}} d x

Apply u-substitution

: \int_{1}^{3} \frac{1}{u ^{2}} d u

= \int_{1}^{3} \frac{1}{u ^{2}} d u

Apply the Power Rule

: [- \frac{1}{u}]_{1}^{3}

= [- \frac{1}{u}]_{1}^{3}

Compute the boundaries:

\frac{2}{3}

= \frac{2}{3}

\int_{1}^{2} (3 x^{2} - 5 x) d x

\int_{1}^{2} k - x d x

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

\int_{a}^{b} e^{- t^{2}} d t

\int_{- 5}^{5} (9 π z + \frac{81 π}{2}) d z
