Example of Definite Integral
- $\ds \int_2^3 2 x \rd x = 5$
Proof
| \(\ds \int_2^3 2 x \rd x\) | \(=\) | \(\ds \bigintlimits {x^2} 2 3\) | Primitive of Power | |||||||||||
| \(\ds \) | \(=\) | \(\ds 3^2 - 2^2\) | Definition of Definite Integral | |||||||||||
| \(\ds \) | \(=\) | \(\ds 5\) | evaluating |
$\blacksquare$
