Area Under A Curve A2 Level Level Revision Maths Pure Mathematics Case 1: curves which are entirely above the x axis. x f (x) a b y x y = f (x) Δ. the curve y = f (x), completely above the x axis. shows a "typical" rectangle, Δx wide and y high. in this case, we find the area by simply finding the integral: \displaystyle\text {area}= {\int { {a}}^ { {b}}} f { {\left ( {x}\right)}} {\left. {d} {x}\right.}. 2. use the formula a = ∫a,b f (x) dx to set up the definite integral. as mentioned in the “summary” section of this article, you need to do a definite integral between two points (limits) in order to determine the area under a curve between those two points. in our example, the function (f (x)) is y=x^2, and the limits are x=0 and x=4.

Figure 6.1.2: (a)we can approximate the area between the graphs of two functions, f(x) and g(x), with rectangles. (b) the area of a typical rectangle goes from one curve to the other. the height of each individual rectangle is f(x ∗ i) − g(x ∗ i) and the width of each rectangle is Δx. adding the areas of all the rectangles, we see that.
