Question

What is a left Riemann sum?

Answer 1

Left Riemann Sum (left endoints as sample points)

`int_a^b f(x) dx approx sum_{i=1}^nf(a+(i-1)Deltax)Delta x`,
where `Delta x={b-a}/n`

Right Riemann Sum (right endpoints as sample points)

`int_a^b f(x) dx approx sum_{i=1}^nf(a+iDeltax)Delta x`,
where `Delta x={b-a}/n`
