How to fill out.
Input the coordinates of the points in the appropriate fields. All coordinates are zero by default, to change it, you need to click on the desired coordinate. If necessary, you can change the name of a point in the box beside the field with coordinates. To derive the solutions you need to click on "Solve".

Examples
To input vector $A↖{\_}$ with coordinates $(-5, 1/5)$ and vector $B↖{\_}$ with coordinates $(3, 1/3)$ you need to fill out the form as follows:

To input vectors ${AB}↖{\_\_}$ и ${CD}↖{\_\_}$, with points А = $(-5, 1/5)$, B = $(2, 9)$, C = $(3, 1/3)$ and D = $(0.1, 0)$ you need to fill out the form as follows:
