.Integral calculus is essential in analyzing accumulation, area under curves, and continuous change. Our calculator focuses on definite integrals, solving them step-by-step with optional graphing.
The definite integral of a function f(x)
over an interval [a, b]
is defined as:
∫ab f(x) dx = F(b) - F(a)
Where F(x)
is an antiderivative of f(x)
.
∫u dv = uv - ∫v du
.π

in bounds for greater precision!Given I(t) = 5e^{-0.1t}
, find charge transferred in 10 seconds:
Q = ∫010 5e^{-0.1t} dt ≈ 31.6 C
Evaluate surplus under a linear demand curve:
