integral from 0 to 1 of (x^2-2x+4)

\int_{0}^{1} (x^{2} - 2 x + 4) d x

\frac{10}{3}

Decimal

3.33333 \dots

Solution steps

\int_{0}^{1} x^{2} - 2 x + 4 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}^{1} x^{2} d x - \int_{0}^{1} 2 x d x + \int_{0}^{1} 4 d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} 2 x d x = 1

\int_{0}^{1} 4 d x = 4

= \frac{1}{3} - 1 + 4

Simplify

\frac{1}{3} - 1 + 4 : \frac{10}{3}

= \frac{10}{3}

\int_{0}^{4} (14 - t) t d t

\int_{1}^{- 1} (6 r + 5)^{2} d r

\int_{0}^{1} sin (x) + cos (x) d x

\int_{0}^{L} sin^{2} (\frac{2 π x}{L}) d x

\int_{- 4}^{4} (\frac{x}{2} + 1) d x
