Waves & Polar
Discover trigonometric functions, periodic behaviour, and the beauty of polar coordinates.
Levels
Tap a level to start exploring. Earn up to 3 stars per level!
Drag the sliders to stretch, squish, and flip a sine wave. Discover what amplitude and frequency mean.
A wave appears on the graph. Identify its equation from the choices.
A ghost wave is shown. Type the equation in y = a·sin(b·x) form to match it.
Adjust the sliders so your polar rose matches the ghost pattern.
Use waves, polar roses, and trig curves to draw smiles, hearts, galaxies, and free-form art!
Ride the waves! Dial in amplitude, frequency, and phase to surf the marble into the goal.
Start with Wave Rider to feel how amplitude, frequency,
and phase control a sine wave. Then venture into polar coordinates
to draw roses, spirals, and more!
Complete all five levels to unlock Wave Runner —
a physics bonus level where you tune the wave to surf the marble into
the goal!
