# Solve - A colorful graphing calculator

by Pomegranate Apps LLC
\$4.99 in the App Store

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.

Unique colorful interface. The colors aren’t there just to pretty things up. They also serve as separate calculators that can interact with each other. For example, if you store an answer within one calculator, you can swipe across the color bar to recall and use it in another calculator.

“Touch to Plot”. Whenever you have an equation with variables that can be plotted a “Touch to Plot” button will appear, allowing you to quickly turn it into a graph.

### For those who...

• It’s ideal for students, teachers, and anyone else in need of a powerful graphing calculator.

### Not for those who...

• The only issue we have with Solve is that there are almost too many features. If all you want is a graphing calculator, you’re getting a lot more than you asked for.

### Why we love it

If you’re tired of lugging around a graphing calculator wherever you go, this is the app for you.

### App Store Description

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 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.

GRAPHING
Plot functions using the x variable. For example, "y=sin(x)" is just entered as "sin(x)".
• cos(x)
• abs(x)
• x^2+2x+6

POLAR GRAPHING
Plot polar equations using the θ variable. For example, "r=2θ" is just entered as "2θ".
• 2θ
• sin(2θ)

3D GRAPHING
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

PLOT MULTIPLE GRAPHS
Graph multiple functions by separating each equation with a comma.
• sin(x),cos(x)
• x,x^2,x^3

TIME GRAPHING
The T variable is used to create animated or time plots.
• cos(x+T)
• sin(x+T)*x
• cos(x+T)+sin(y+T)
