Beautiful Functions

Explore linear, quadratic, cubic, and logarithmic functions for free - and go deeper with trigonometric, rational, and absolute value functions.

Beautiful Functions is a visual math playground that lets you experiment, adjust, and understand how functions behave. Move sliders, observe graph changes in real time, and discover mathematical patterns through intuitive interaction.

Included for free:
• Linear functions: y = ax + b
• Quadratic functions: y = ax² + bx + c
• Cubic functions: y = ax³ + bx² + cx + d
• Logarithmic functions: y = logₐ(x).

Unlock even more with a single in-app purchase:
• Trigonometric functions: sine, cosine, tangent, etc.
• Rational functions with asymptotes and removable discontinuities
• Absolute value functions: |x - a|, and their properties
• Linear function transformations: shifts and reflections.

All functions come with detailed explanation cards, color-coded sliders, and interactive graphs that respond to your input instantly.

Perfect for:
• Students wanting to master core function types
• Parents and tutors supporting math learning
• Anyone who believes math can be beautiful.
