integral from 3.3 to 8.3 of 12x^2-6x+4/x

\int_{3.3}^{8.3} 12 x^{2} - 6 x + \frac{4}{x} d x

1973.08933 \dots

Solution steps

\int_{3.3}^{8.3} 12 x^{2} - 6 x + \frac{4}{x} 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_{3.3}^{8.3} 12 x^{2} d x - \int_{3.3}^{8.3} 6 x d x + \int_{3.3}^{8.3} \frac{4}{x} d x

\int_{3.3}^{8.3} 12 x^{2} d x = 2143.39999 \dots

\int_{3.3}^{8.3} 6 x d x = 174

\int_{3.3}^{8.3} \frac{4}{x} d x = 3.68933 \dots

= 2143.39999 \dots - 174 + 3.68933 \dots

Simplify

= 1973.08933 \dots

\int_{- 1}^{0} 3 e^{5 t - 8} d t

\int_{- 1}^{0} \frac{x}{1 + x} d x

\int_{1}^{2} sin (2 θ) cos (3 θ) d θ

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

\int_{0}^{1} x^{3} (4 + x^{4})^{3} d x
