QuickStart GuideWhen you enter a function, the calculator will begin by expanding (simplifying) it. Next, the calculator will plot the function over the range that is given. Use the following guidelines to enter functions into the calculator. VariablesYou must use a lowercase 'x' as the independent variable. ExponentsExponents are supported on variables using the ^ (caret) symbol. For example, to express x^{2}, enter x^2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and BracketsParentheses ( ) and brackets [ ] may be used to group terms as in a standard equation or expression. Multiplication, Addition, and SubtractionFor addition and subtraction, use the standard + and  symbols respectively. For multiplication, use the * symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying parentheses, example: (x + 1)(x  1). Order of OperationsThe calculator follows the standard order of operations taught by most algebra books  Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radicals, FractionsThe above features are not supported at this time. A future release will add this functionality.
