Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

partial-differential-equations

Fourier cosine series

taught

Expand a function on [0, L] in a series of cosines alone, computing each coefficient directly from orthogonality rather than a memorized formula.
