This is a program that makes plot of funcions. 1.First write the funcion using [1] to X. This program only supports +-x:() Exemple: ([1]x[1]-[1])x3 2.Then you have to write the scale of y: the number of unities from y=0 to y=180 (and from 0 to -180) 3.Then you have to write the scale of x: the number of unities from x=0 to x=240 (and from 0 to -240) 4.Then you write the numbers that the y lines match Exemple: if you write 10, he program will make a line at every 10 unities. 5.Then you write the numbers that the x lines match 6.Then you write the y number that the program will start 7.Then you write the y number that the program will finish 8.Finaly you write the number of points the program will mark in total Now you have your plot.
