Interactive Math Tools

Free, hands-on visualisations for O-Level and JC math — drag, play and explore the concepts that are hard to see on paper.

Trigonometric Graphs Explorer

Plot y = a·sin(bx + c) and friends — drag, scale and shift to see how each parameter reshapes the wave.

See how translations, stretches and reflections reshape any graph in real time.

Sketch polynomials and rational curves; find the turning points, asymptotes and intercepts.

Plot complex numbers, add and multiply them, and watch modulus–argument geometry come alive.

Rotate vectors, lines and planes in 3D to build intuition for H2 vectors.

Rapid-fire differentiation and integration practice with instant feedback.

Timed arithmetic drills to sharpen speed and accuracy.

Watch a point circle the unit circle and unroll into the sine and cosine waves — see why they're the same motion, a quarter-turn apart.
