Ned, You might say that F(x) increases whenever f(x) > 0 and F(x) decreases whenever f(x) < 0, going along horizontally when f(x) = 0. --Nelson From: Ned Granic To: maths@xxxxxxxxxxxxx Sent: Thursday, December 07, 2006 9:42 AM Subject: [maths] follow up on my last one -- integrals With regard to rough sketches of integrals, this particular problem says: Make a rough sketch of an integral F given that F(0) = 2. The f curve is on an x y grid; y scale is 0 to 2, x scale is 0 to 5. It starts at (02) and ends at (4.2) Between (0,2) and (2,2) it dipps down to (1,1) and then at (2,2) it suddenly curves up to(3,3), and then it curves back down to (4.2). W/o calculating the points, what should the graph of F roughly look like? Many thanks in advance again! Ned
