integral from 4.9 to 7.1 of 12x^2-6x+4

\int_{4.9}^{7.1} 12 x^{2} - 6 x + 4 d x

890.648

Solution steps

\int_{4.9}^{7.1} 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_{4.9}^{7.1} 12 x^{2} d x - \int_{4.9}^{7.1} 6 x d x + \int_{4.9}^{7.1} 4 d x

\int_{4.9}^{7.1} 12 x^{2} d x = 961.048

\int_{4.9}^{7.1} 6 x d x = 79.2

\int_{4.9}^{7.1} 4 d x = 8.8

= 961.048 - 79.2 + 8.8

Simplify

= 890.648

\int_{0}^{20} \frac{1}{2} x d x

\int_{- π}^{\frac{π}{2}} sin (x) d x

\int_{0}^{1} (7 x^{e} + 8 e^{x}) d x

\int_{0}^{2 π} 9 cos^{2} (t) d t

\int_{3}^{\infty} \frac{1}{9 + x ^{2}} d x
