WebThe definite integral of a function gives us the area under the curve of that function. Another common interpretation is that the integral of a rate function describes the accumulation of the quantity whose rate is given. We can approximate integrals using Riemann sums, and we define definite integrals using limits of Riemann sums. WebDecoding the Integral. My calculus conundrum was not having an intuition for all the mechanics. When we see: $\int \sin(x) dx$ We can call on a few insights: The integral is just fancy multiplication. Multiplication accumulates numbers that don't change (3 + 3 + 3 + 3). Integrals add up numbers that might change, based on a pattern (1 + 2 + 3 ...
