Riemann sums are a fundamental method in calculus used to approximate the total area under a curve by dividing it into several simple shapes (usually rectangles). As the number of rectangles increases to infinity, the sum converges to the definite integral. The Riemann sum for a function over an interval divided into subintervals is:
[ \int_a^b f(x) , dx \approx S_n = \sum_i=1^n f(x_i^*) \cdot \Delta x ] sumas de riemann ejercicios resueltos pdf
