Maths you can grasp
Move the sliders, observe, understand. Here maths comes alive — right in your browser.
🎛️ Function plotter
Choose a function type and drag the sliders for a, b and c. Watch how each parameter changes the graph.
📊 Riemann sums
The integral is the area under the curve. Increase the number of rectangles and watch the approximation converge to the true value.
🚀 Projectile motion
Set the angle and speed and hit launch. The ball flies a parabola — physics meets quadratic functions.
🔵 Unit circle → sine
A point rotates on the circle — its height traces the sine wave. The classic way to really understand sin and cos.
📈 Derivative live
A point moves along f(x), the tangent tilts with it. Its slope is exactly the value of the derivative f'(x) — drawn alongside.
Where f(x) rises, f′(x) is positive; where f(x) falls, f′(x) is negative. At the peaks/troughs, f′(x) = 0.
🌊 Double-slit experiment
Two slits act as wave sources. The waves overlap and create a striped pattern on the screen (interference). Play with wavelength and slit spacing.
Larger slit spacing or shorter wavelength → narrower fringes.
⚛️ Atom – shell model
Electrons orbit the nucleus in shells. Choose an element and see how the electrons distribute by the 2, 8, 8 scheme.
🌫️ Quantum orbitals (s, p, d)
The modern atomic model: no fixed orbits, but electron clouds. Each dot is a possible location (probability |ψ|²). Choose an orbital — the cloud rotates to show the 3D shape.
Each dot is a possible location of the electron (∝ |ψ|²). The cloud rotates to show the 3D shape.
