Click the green flag; you will be prompted to input an equation. Notice that the left side of the equation is already there for you; you only need to type in the right side. This engine supports: -operators: + - * / ^ √ sin cos -parenthesis: ( ) -absolute value: | | (e.g. |-5| would mean 5) -the variable: x Enter something that the calculator doesn't support and it will just interpret it as 0 Some interesting graphs: 50sinx^2 50sin(x^2) (50sinx)^2 (50((sinx)^2))-24.99 100/x 3*√|x| x^2/50 50*sin(x) 50*sin|x| |50*sin(x)|
