Key Concepts

Area Under a Curve

Calculating the area under a curve involves integrating the function that describes the edge of a region over a specific interval. This process allows for the determination of the total accumulated quantity or geometric space enclosed by the curve and the interval boundaries.

Evaluation of Integrals

Evaluating an integral exactly requires finding an antiderivative of the integrand and then using the Fundamental Theorem of Calculus to compute the difference between the values of the antiderivative at the upper and lower limits of the interval. This process yields the precise area or accumulated value represented by the integral.

Riemann Sum

A Riemann sum is a way of approximating the area under a curve by breaking the region into narrow strips (rectangles) and summing the areas of these pieces. As the number of strips increases and their width decreases, the Riemann sum approaches the exact area, serving as the foundation for the concept of integration.

Definite Integral

A definite integral represents the exact signed area under a curve between two specified bounds. It is defined as the limit of a Riemann sum as the width of the subintervals approaches zero, and it is computed by finding the antiderivative of the function and then applying the Fundamental Theorem of Calculus.
