Key Concepts

Definite Integral

A mathematical expression that represents the exact area under a curve over a specific interval. It is defined as the limit of a Riemann sum as the number of subdivisions approaches infinity, thus capturing the accumulated value of a function between two bounds.

Trigonometric Functions

Functions that relate the angles of a triangle to the ratios of its sides, with properties that are critical in many areas of mathematics. In this context, the tangent function, which is continuous over the interval considered, serves as the integrand whose area under the curve is being approximated.

Area Under a Curve

A fundamental concept in calculus where the area between a function's graph and the horizontal axis over a certain interval is computed. This area is typically evaluated using a definite integral, which sums up infinitesimally small rectangles under the curve.

Riemann Sum

A method for approximating the area under a curve by dividing the interval into small subintervals, evaluating the function at specific points within these subintervals, and then summing up the products of these function values with the subinterval widths. As the number of subintervals increases indefinitely, the Riemann sum converges to the definite integral.
