tags Math These are the two ways we commonly think about definite integrals: they describe an accumulation of a quantity, so the entire definite integral gives us the net change in that quantity.1 Why Integral Calculus # Figure 1 represents 2 graphs of y = cos(x). Let’s say we would like to calculate the area of \( x_1 \) . We could calculate the area by aproximation, for example, Graph B is filled with the area we would like to calculate, so we could divide this area by equal sections of \(\Delta x_n\) from a to b rectangles, then we could calculate the area of these rectangles by \(f(x_i) * \Delta x_n\) where \(f\) is the area of each of the rectangles. ...
