integral from 3 to 4.3 of (12x^2-6x+4)

\int_{3}^{4.3} (12 x^{2} - 6 x + 4) d x

186.758

Solution steps

\int_{3}^{4.3} 12 x^{2} - 6 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_{3}^{4.3} 12 x^{2} d x - \int_{3}^{4.3} 6 x d x + \int_{3}^{4.3} 4 d x

\int_{3}^{4.3} 12 x^{2} d x = 210.028

\int_{3}^{4.3} 6 x d x = 28.47

\int_{3}^{4.3} 4 d x = 5.2

= 210.028 - 28.47 + 5.2

Simplify

= 186.758

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

\int_{0}^{2 π} cos^{6} (x) d x

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

\int_{3}^{6} (x^{2} - 6 x + 9) d x

\int_{0}^{l n (A)} 9 e^{3 x} d x
