integral from-14 to 1 of x|49-x^2|

\int_{- 14}^{1} x 49 - x^{2} d x

- \frac{23913}{4}

Decimal

- 5978.25

Solution steps

\int_{- 14}^{1} x 49 - x^{2} d x

Eliminate Absolutes

= \int_{- 14}^{- 7} x (- 49 + x^{2}) d x + \int_{- 7}^{1} x (49 - x^{2}) d x

\int_{- 14}^{- 7} x (- 49 + x^{2}) d x = - \frac{21609}{4}

\int_{- 7}^{1} x (49 - x^{2}) d x = - 576

= - \frac{21609}{4} - 576

Simplify

- \frac{21609}{4} - 576 : - \frac{23913}{4}

= - \frac{23913}{4}

e^{t} sin (9 t)

\frac{d}{d x} (sin (\frac{π x}{2}))

\int \frac{3 x ^{2} + 6 x + 2}{x ( x + 1 ) ^{2}} d x

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

\frac{\partial}{\partial y} (\frac{2 x}{x ^{2} + y ^{4}})
