01 · Mathematics
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.”

Frequently Asked Questions
Everything you need to know about learning, authoring, and enrolling on T2S.
How does T2S differ from traditional video courses?
Traditional platforms rely on passive video consumption. T2S embeds live KaTeX equations, programmable TikZ diagrams, and interactive parameter sliders directly in each lesson so you manipulate variables and understand how concepts behave in real-time.
Are free sample lessons available before enrolling?
Yes. Every course features open introductory preview lessons so you can experience the interactive teaching format before registering or enrolling.
How can educators publish courses on T2S?
STEM educators can apply via our "Teach on T2S" program to access our full authoring suite — including LaTeX math formulas, TikZ vector generators, and interactive question engines.
Do students receive completion certificates?
Yes, all certificate courses include verified digital completion certificates upon finishing chapters and passing end-of-module assessments.
