Interactive labs

Pick a topic. Every lab has live readouts, guided lessons and questions to test yourself.

Function & Graph Explorer

Plot lines, quadratics and any function you type. Drag a, b, c and watch the curve morph.

Class 9, 10, 11, 12

Trigonometry & Height-Distance

A unit circle with live ratios, plus real angle-of-elevation problems you solve by dragging.

Class 10, 11

Statistics & Probability

Flip, roll and draw thousands of times and watch chance settle onto theory. Build histograms.

Class 9, 10, 11, 12

Geometry & Constructions

Drag triangles and quadrilaterals to test angle sums, congruence, similarity and Pythagoras. Follow compass-and-ruler constructions step by step.

Class 9, 10

Circles & Conic Sections

Test the circle theorems and tangents, work out arcs and sectors, then meet the parabola, ellipse and hyperbola with draggable foci and eccentricity.

Class 9, 10, 11

Calculus Lab

Approach a limit, shrink a secant into a tangent, find maxima and minima, and watch rectangles add up to an integral.

Class 11, 12

Matrices & Transformations

Drag a matrix and watch the plane turn, stretch and flip, then multiply, invert and solve systems with every step shown.

Class 12

Maths Explainers

Repeating decimals, the Argand plane, counting trees, series, Venn diagrams and linear programming, all draggable.

Class 9, 10, 11, 12

Mensuration & 3D Shapes

Rotate cones, cylinders, spheres and frustums in 3D; resize them for live areas and volumes; unfold the nets; melt one solid into many.

Class 9, 10

Vectors & 3D Geometry

Drag vectors, turn a 3D scene, and see dot and cross products, skew lines, planes and shortest distances.

Class 11, 12

Vedic Math Shortcuts

Multiply by 11 in your head, square a number ending in 5, and learn the one method that always works. Practice each trick live.

Class 8, 9, 10, 11, 12

Learn, practise and explore

Lessons ship inside every lab. These pages arrive alongside them.

50 Maths Myths & Paradoxes

0.999… = 1, dividing by zero, and other things that break your intuition.

Maths Quiz

Class-wise questions with explanations.

Maths Games

Quick drills to make it stick.

Formula Sheet

Every formula, with where it is used.

History

25 mathematicians and ideas, from Pythagoras to linear programming.

Why "Shunya"? Shunya (शून्य) is Sanskrit for zero — the idea that made modern mathematics possible. Zero is why $a + 0 = a$ and $a \times 0 = 0$ hold for every number. The labs are built the same way as iLabs' chemistry and physics labs: real formulas running live, a lesson for every class, and nothing to install.
