Quadratic equations, unboxed
No more blind memorization. See how Class 10 CBSE (Ch. 4) quadratic equations model real-world paths.
Change the a, b, and c coefficients below and instantly watch the roots slide along the horizontal axis in real time — the discriminant recalculates as you drag.
Notice how Δ < 0 lifts the parabola above the axis, eliminating real roots, while Δ > 0 guarantees two distinct intercepts.

Problem
A projectile's height over time is h = −5t² + 20t. When does it hit the ground?
Watch the algebra solve itself line by line. The active step is highlighted — previous steps stay visible so you never lose track of where a number went.
02 · Physics
Light & refraction, simulated
Master Class 10 (Ch. Light — Reflection and Refraction) with full ray tracing and timeline playback.
Incident rays parallel to the principal axis refract through the principal focus F, while central rays pass undeflected through the optical centre O.
Use the video timeline scrubber below the figure to pause, rewind, and examine the light ray trajectory at any millisecond — like a precision optical bench.

“I always memorized formulas without knowing what they did. Seeing the graphs move when I change numbers finally made calculus click for me.”
“The physics simulations are incredible. Being able to pause a ray or projectile and inspect the vectors at that exact moment is like a superpower.”
“So much better than a static textbook. The diagrams that actually show processes happening helped me score an A in my finals.”
