Secant & Cosecant
Graph sec(x) and cosec(x) against their base cos/sin curves. See exactly where the asymptotes come from, and reshape the curve with amplitude and frequency controls.
Solar System
Watch the planets orbit the Sun in real proportion of speed. Zoom and pan freely, then click any planet to pull up its stats — size, distance, orbit, moons and more.
Spaceship Flight
Take the cockpit and fly the solar system in first person. Steer with the arrow keys, burn hard past Jupiter, and pull up telemetry by flying close to a planet.
