Math Surface

3D surfaces, 2D curves, the complex plane, probability — all in one app. Type a formula and watch it come alive. Perfect for study, exploration, or just enjoying the beauty of math.

Description:
MathSurface turns equations into shapes you can hold, spin, and slice. It's a math playground for iPhone and iPad — designed for students, curious minds, and anyone who learns better by seeing.

■ Features
• 3D surface plots: visualize z = f(x, y) with smooth rotation and pinch-to-zoom • 2D function plots: explicit y = f(x) or implicit 0 = F(x, y) curves
• Complex plane: loci such as |z − α| = r, arithmetic operations, powers, and n-th roots of unity • Probability distributions: binomial and normal, controlled by live sliders
• Surface of revolution: spin any 2D curve around the x- or y-axis (rendered with SceneKit) • Cross sections: slice any 3D surface with a plane and see the resulting curve
• Compare mode: overlay two functions in the same plot
• Preset gallery: paraboloid, monkey saddle, Mexican hat, lemniscate, and many more
• Favorites: save your own custom expressions for instant recall

■ Who it's for
• High school and university students studying calculus, analysis, or probability
• Teachers looking for live visual aids
• Anyone curious about how a formula actually looks
• People who just enjoy beautiful math

A custom Liquid Glass–style formula keyboard makes entering sin, cos, √, π, and friends quick and natural. The dark neon UI keeps the math front and center.
