A definite integral is when you integrate a function over a specified interval. When completed you have a definite answer.

Definite Integral because it is bounded

$\int_{0}^{1} 3 x d x$ $int_0^1 3xdx$ evaluates to $[\frac{3 {(1)}^{2}}{2} - \frac{3 {(0)}^{2}}{2}] = \frac{3}{2} - 0 = \frac{3}{2} = 1.5$ $[(3(1)^2)/2 - (3(0)^2)/2] = 3/2 - 0 = 3/2=1.5$

Indefinite Integral because it is not bounded

$\int 3 x d x$ $int 3x dx$ evaluates to $\frac{3 x^{2}}{2} + C$ $(3x^2)/2 + C$
