integral of 10xe^{3x^2-7}

\int 10 x e^{3 x^{2} - 7} d x

\frac{5}{3} e^{3 x^{2} - 7} + C

Solution steps

\int 10 x e^{3 x^{2} - 7} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10 \cdot \int x e^{3 x^{2} - 7} d x

Apply u-substitution

: \int \frac{e ^{u}}{6} d u

= 10 \cdot \int \frac{e ^{u}}{6} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10 \cdot \frac{1}{6} \cdot \int e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= 10 \cdot \frac{1}{6} e^{u}

Substitute back

u = 3 x^{2} - 7

= 10 \cdot \frac{1}{6} e^{3 x^{2} - 7}

Simplify

10 \cdot \frac{1}{6} e^{3 x^{2} - 7} : \frac{5}{3} e^{3 x^{2} - 7}

= \frac{5}{3} e^{3 x^{2} - 7}

Add a constant to the solution

= \frac{5}{3} e^{3 x^{2} - 7} + C

\int 3 cos (x) - 2 sin (x) d x

x \to π lim (cos (\frac{5}{3} x))

\frac{x - 8}{x + 8}

e^{x} + 1, at x = 0

\int (3 + 2 x)^{- 3} d x
