First, imagine a curve drawn on a graph. The integral measures the space between that curve and the horizontal axis. Mathematically, we write this as the definite integral of a function f(x) from a to b, symbolized by the integral sign and limits. The process of finding an integral is called integration. It can be done analytically with formulas or numerically using methods like the trapezoidal rule. In summary, integrals help us compute areas, volumes, and accumulated quantities, making them essential in physics, engineering, and economics.
