GraphPaper is an app that can graphically represent any 1-variable or 2-variable equation you can think of in. By default x and y are used as the variables. A set of common expressions are provided to start you up. All the features are available by swiping from the bottom or the top. It features ability to display multiple graphs on top of each other with the "Hold" function, trace feature allows you to view the values of a 1-variable graph in detail, any mathematical expression containing x and y or only x can be represented, a drop down list contains all the known functions if you do not want to type them in, known functions: sin(x), cos(x), tan(x), asin(x), acos(x), atan(x), abs(x), sqrt(x), pow(x,2), round(x), exp(x), ln(x), log(x,2), log10(x), step(x), ramp(x), known constants: "pi" and "e", display the integral or the derivative of a 1-variable expression, display the Cartesian or the polar form of a 1-variable expression, and thickness and color customization.
