integral from 0 to 4 of (x^2-4x+3)

\int_{0}^{4} (x^{2} - 4 x + 3) d x

\frac{4}{3}

Decimal

1.33333 \dots

Solution steps

\int_{0}^{4} x^{2} - 4 x + 3 d x

Apply the Sum Rule:

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

= \int_{0}^{4} x^{2} d x - \int_{0}^{4} 4 x d x + \int_{0}^{4} 3 d x

\int_{0}^{4} x^{2} d x = \frac{64}{3}

\int_{0}^{4} 4 x d x = 32

\int_{0}^{4} 3 d x = 12

= \frac{64}{3} - 32 + 12

Simplify

\frac{64}{3} - 32 + 12 : \frac{4}{3}

= \frac{4}{3}

4 t \frac{d y}{d t} - 5 y = t

\int - 2 \cdot 3^{6 x} d x

y = cot^{2} (x)

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

x \to 3 lim (π)
