Solve is a calculator like no other! Solve solves expressions as you type and features an innovative memory system to store and recall answers. Simply touch the answer to store it and touch the stored answer to use it in an expression.Solve has four tabs that select four different calculators each with its own color. Multiply numbers, calculate a tip and find a square root all without clearing your results! Plot graphs with a single touch! Solve plots 2D and 3D functions using the x, y and variables. When you use the x, y and variables in an equation the answer will say Touch to Plot. Touch this label to graph the equation.GRAPHINGPlot functions using the x variable. For example, "y=sin(x)" is just entered as "sin(x)". cos(x) abs(x) x^2+2x+6POLAR GRAPHINGPlot polar equations using the variable. For example, "r=2" is just entered as "2". 2 sin(2)3D GRAPHINGPlot 3D functions by using the x and y variables. For example, "z=x+y" is just entered as "x+y". cos(x)+sin(y) x^2+y^2PLOT MULTIPLE GRAPHSGraph multiple functions by separating each equation with a comma. sin(x),cos(x) x,x^2,x^3TIME GRAPHINGThe T variable is used to create animated or time plots. cos(x+T) sin(x+T)*x cos(x+T)+sin(y+T)
