A small Raylib app for visualising a sample integral. AI Generated to play with the visualisation not for code quality.

integral from -pi/2 to pi/2  cos(x) / (1 + e^x)  dx = 1

You can watch the weighted cosine curve, the accumulated area function F(x), the mirrored pairing f(x) + f(-x), and the denominator rewrite all line up on screen.

f(x) = cos(x) / (1 + e^x)
F(x) = integral from -pi/2 to x  f(t) dt
