Now, the general integral of r · dr is 1 2r2. Therefore, A = 2π [1 2r2]r = Rr = 0; orA = 2π [1 2R2 − 1 2(0)2]; whence A = πR2. Another Exercise. Let us find the mean ordinate of the positive part of the curve y = x − x2, which is shown in Figure 60 .

NettetThe more general form of area between curves is: A = ∫ b a f (x) −g(x) dx because the area is always defined as a positive result. So for this problem, you need to find all intersections between the 2 functions (we'll call red f (x) and blue g(x) and you can see that there are 4 at approximately: −6.2, −3.5, −.7, 1.5.
