## anonymous one year ago List x1, x2, x3, x4 where xi is the right endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 3 and x = 5.

1. Zarkon

$x_i=3+i\times\Delta x$ where $$\Delta x=\dfrac{5-3}{4}$$

Would I use 3 4 and 5 as my i values?

3. Zarkon

no

4. Zarkon

$\Delta x=\frac{5-3}{4}=\frac{2}{4}=\frac{1}{2}$ $x_i=3+i\times\frac{1}{2}$ $x_1=3+1\times\frac{1}{2}=3.5$ $\cdots$
