About
Learn math by watching it happen.
MathLens teaches one small step at a time, and the picture changes with every step. You see why an idea works before you have to remember the formula.
What's here
Free lessons on calculus, linear algebra, Fourier series and probability, each with a visual you can drag and play with. Graph Lab, a free graphing calculator for 2D and 3D. And the tutor, which writes a step-by-step lesson with its own visualization for any question you ask, or for a paper you upload.
Who it's for
Students who want to understand a topic instead of memorising it, people going back over math they half remember, and anyone reading a paper full of equations they'd like to see in motion.
Who runs it
MathLens is run by SAMYAK BAID K in Coonoor. Questions, ideas and bug reports are welcome at [email protected].
