3. Developing the Riemann Sum and Limit Definition of a Definite Integral Q:How do we get a better approximation of area? So, shrinking the length of the bases for every subinterval so they approach zero leads us to… …Which is the limit definition of the definite integral for f on [a, b]. or the length of each subinterval. Which leads us to…
