Tangents, cost-revenue, integration area, slope field — visually explore karo!
Function choose karo aur point x drag karo. Tangent line live update hogi — slope = f'(x) dikhega!
Fixed cost aur marginal cost change karo. C(q), R(q), P(q) graphs dekho aur maximum profit point identify karo!
Limits a aur b drag karo. Riemann rectangles se area approx dikhega aur exact integral bhi!
dy/dx = f(x,y) ka slope field dekho. Canvas par click karo aur solution curve draw hogi — exponential growth visually!
