Ask the page you're reading.
Chatability sits inside your PDF reader. Capture any part of a page and ask about exactly that. When words aren't enough, it builds a live, interactive demo of the concept, in the chat, in about a minute.
The infinite square well
Inside the well the particle obeys −(ℏ2/2m)ψ″ = Eψ, with ψ(0) = ψ(a) = 0. The only solutions that survive both walls are ψn(x) = √(2/a) sin(nπx/a), each carrying energy En = n2π2ℏ2/2ma2.Three pages, three instruments.
Everything below was produced by Chatability itself: a page was captured from a real textbook, one question was asked, and the pipeline answered with a working instrument. Unedited output. Use them, they're live.
Quantum mechanics
A particle in the infinite square well has stationary states ψn(x) = √(2/a) sin(nπx/a) and a general state is a superposition of them evolving in time.Abstract algebra
The eight motions of a square, R0, R90, R180, R270, H, V, D, D′, close under composition: the dihedral group D4, tabulated by Cayley.Engineering mathematics
The ratios sin θ, cos θ, tan θ are read off a unit circle; swept through 360° they trace the waveforms every AC circuit runs on.It lives where you read.
