in Desmos there should be a plus sign right above the list of your equations on the left side. Click that plus sign and then click "table". then enter your numbers. then your points will be shown on the graph

to turn this into a line long press on the button next "y" on the table you have made, then select "lines"

Use a change of variables to find the indefinite integral xe^(x^2) dx

ValentinkaMS [17]

$\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12\int2xe^{x^2}\,\mathrm dx$

If we take $y=x^2$ , then $\mathrm dy=2x\,\mathrm dx$ , and we can write the above integral as

$\displaystyle\frac12\int e^y\,\mathrm dy=\frac12e^y+C$

and undoing the substitution, we end up with

$\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12e^{x^2}+C$
