This is a graphing calculator application. It can be used to visualize functions of many different types and complexities.
Standard Edition for standard computers.
Fast Edition for slow computers. Draws a line much faster in exchnge for lower precision.

All PEMDAS rules, including parentheses, are taken into account. There is no limit to how many nested parentheses and functions can exist in a user's equation.
The graph plane can be moved in any direction using the circular navigation pad, and can be zoomed in and out using the +/- buttons. The dimentions of the plane can also be set manually using the max/min input boxes at the top right.
Previously entered functions can be recalled using the back/forward arrow buttons to the right of the equation input box.
This graphing calculator will notify the user of errors in the function they are trying to graph. There are four categories of errors.
- Unbalanced parentheses. When there are not the same number of open and closed parentheses.
Unclosed parentheses
"sin(2 - x"
Two extra close parentheses
"3(x + 5)(log(x^3) -4)))"
- Unrecognized element. When a user enters a letter, symbol, or any equation element that the calculator doesn't know.
Unrecongized element starting with "L"
"LOL i dont wanna graff"
Unrecongized element starting with "c"
"log(5x) * csc(x)"
- Invalid use of an operator. When the user tries to use an operator incorectly or in the wrong context.
Incorrect use of + operator
"(5x + )"
Incorrect use of / operator
"3 // x"
- Invalid x/y parameters set. When the user sets the X/Y Minimum value to be equal to or greater than the X/Y Maximum value.
Graph plane cannot have width of 0
X Min = 2
X Max = 2
Graph plane cannot have negative/reversed height
Y min = 5
Y Max = -1
Multiplication can be entered as a "*" multiplication symbol 2 * x, or without any symbol 2x.
