"Solve is a calculator like no other! Whether you need a simple calculator for everyday use or a graphing calculator for high school math, Solve is everything you'll ever need in a calculator app. Featuring an innovative memory system to store and recall answers, Solve has four tabs that select four different calculators each with its own color. Multiply numbers, plot a graph and solve an equation all without clearing your results! Solve also includes several interactive tutorials to help you get started. HELPFUL TIPS Swipe the button pad left and right to reveal more buttons, options and tutorials. GRAPHING INSTRUCTIONS Solve plots 2D and 3D functions using the x, y and θ variables. When you use the x, y and θ variables in an equation the answer will say Touch to Plot. Touch this label to graph the equation. Plot 2D functions using the x variable. For example, "y=sin(x)" is just entered as "sin(x)". • cos(x) • abs(x) • x^2+2x+6 Plot polar equations using the θ variable. For example, "r=2θ" is just entered as "2θ". • 2θ • sin(2θ) Plot 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^2 Graph multiple functions by separating each equation with a comma. • sin(x),cos(x) • x,x^2,x^3 The T variable is used to create animated or time plots. • cos(x+T) • sin(x+T)*x • cos(x+T)+sin(y+T)"
