Question

please integrate this as a limit of a sum. Step by step answer needed.

Answer 1

i have used the limit

$limit \: x \: tends \: to \: 0 \\ \: \: \frac{1 - {e}^{x} }{x} \: = - 1$

just remember limit of sum is just breaking the area to be calculated into small rectangles and adding their indivisual areas to get the total area.
