Question

Resolva a integral definida (x² + 2 ) com intervalo de (0)e (1)

Answer 1

$\int\limits^1_0 {(x^2 + 2)} \, dx$

= $\int\limits^1_0 {x^2} \, dx + \int\limits^1_0 {2} \, dx$

= $\frac{x^3}{3} + 2x \left[\begin{array}{ccc}1\\0\\\end{array}\right]$

= $\frac{1^3}{3} + 2.(1) - [ \frac{0^3}{3} + 2.(0)]$

= $\frac{1}{3}+2$

= $\frac{1+6}{3}$

= $\frac{7}{3}$
