Using commands you can produce new and modify existing objects.
Note: A command's result may be named by entering a label followed by an equal sign (=). In the example below, the new point is named S.
Example: To get the
intersection point of two lines g and h you can enter
S = Intersect[g, h] (see
command Intersect).
Note: You can also use indices within the names of objects: A1 is entered as A_1 while SAB is created using s_{AB}.
