integral from 1 to 2 of x^{-2}

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

\frac{1}{2}

Decimal Notation

0.5

Solution steps

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

Apply the Power Rule

: [- \frac{1}{x}]_{1}^{2}

= [- \frac{1}{x}]_{1}^{2}

Compute the boundaries:

\frac{1}{2}

= \frac{1}{2}

y = \frac{16}{x ^{2} - 6 x - 55}, x = - 3, x = 3

\int \frac{x ^{2} + 132 x + 132}{x ^{3} - 4 x} d x

\int \frac{e ^{x}}{e ^{2 x} - e ^{x}} d x

\frac{\partial}{\partial z} (ln (x))

\int \frac{x}{3 x ^{2} - 1} d x
