integral from 2 to 6 of 8t^3-6t^{-2}

\int_{2}^{6} 8 t^{3} - 6 t^{- 2} d t

2558

Solution steps

\int_{2}^{6} 8 t^{3} - 6 t^{- 2} d t

6 t^{- 2} = \frac{6}{t ^{2}}

= \int_{2}^{6} 8 t^{3} - \frac{6}{t ^{2}} d t

Apply the Sum Rule:

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

= \int_{2}^{6} 8 t^{3} d t - \int_{2}^{6} \frac{6}{t ^{2}} d t

\int_{2}^{6} 8 t^{3} d t = 2560

\int_{2}^{6} \frac{6}{t ^{2}} d t = 2

= 2560 - 2

Simplify

= 2558

\int_{- 5}^{5} (x^{2} - 3) d x

\int_{4}^{6} \frac{3 x - 4}{x ^{2} - x - 6} d x

\int_{0}^{4} π (4 x - x^{2})^{2} d x

\int_{0}^{1} 13 x^{3} 1 - x^{2} d x

\int_{1}^{7} 5 d x
