Maths labs
Seven interactive labs for Class 10โ12 and JEE: drag graphs, spin the unit circle, shrink a secant into a tangent and roll a thousand dice in a second.
Function Transformer
Stretch, flip and slide eight parent graphs, by sliders or by dragging the curve itself.
Unit Circle & Trig Graphs
Walk a point around the circle and watch sine and cosine unroll into waves. You can even hear sin ฮธ.
Complex Numbers
Add, multiply and divide on the Argand plane, and see powers spiral and roots of unity form polygons.
Conic Sections
One slider (eccentricity) turns an ellipse into a parabola and then a hyperbola. PF = eยทPD, live.
Derivatives: Secant to Tangent
Shrink h and watch the secant become the tangent, with the derivative graph drawn alongside.
Integration & Riemann Sums
Fill the area under a curve with rectangles or trapezoids and watch the error fall as n grows.
Probability Lab
Coins and dice, thousands of times: the law of large numbers and why 7 is the commonest sum.
