You are given the four points in the plane a=(-2,2), b=(1,-3), c=(3,6), and d=(7,-3). The graph of the function consists of the three line segments AB, BC and CD. Find the integral by interpreting the integral in terms of sums and/or differences of areas of elementary figures
Let A, B, C, and D be four distinct points in the plane. Suppose that no three of them lie on a line and A, C are on opposite sides of the line BD. The lengths of the line segments AB, BC, CD and DA are 1, 2, 3 and 4 respectively. (a) What is the range of possible values for the length x of the line segment BD? You should justify your answer carefully! [5 marks] (b) Now suppose...

EXAMPLE 4 Evaluate the following integrals by interpreting each in terms of areas. (a) y=V25-2 lov ✓ 25 - 2 dx or 10 + y = 25 (x - 3) dx SOLUTION (a) Since Rx) = V25 - x2 > 0, we can interpret this integral the area under the curve y = 25 - X2 from 0 to But we get x2 + y2 = 25, which shows that the graph of ris a quarter-circle with radius in the...
