integral from-1 to 1 of e^y-(y^2-4)

\int_{- 1}^{1} e^{y} - (y^{2} - 4) d y

e - \frac{1}{e} + \frac{22}{3}

Solution steps

\int_{- 1}^{1} e^{y} - (y^{2} - 4) d y

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 1}^{1} e^{y} d y - \int_{- 1}^{1} y^{2} - 4 d y

\int_{- 1}^{1} e^{y} d y = e - \frac{1}{e}

\int_{- 1}^{1} y^{2} - 4 d y = - \frac{22}{3}

= e - \frac{1}{e} - (- \frac{22}{3})

Simplify

= e - \frac{1}{e} + \frac{22}{3}

\int 4 e^{x} + cos (\frac{x}{5}) d x

\int \frac{1}{5 + x ^{2}} d x

\int \frac{tan ^{4} ( x )}{sec ^{7} ( x )} d x

\int 3 sin^{2} (t) cos (t) d t

\int x^{4} e^{3 x} d x
