OK I have a v-t graph and I wish to find the change in displacement/distance/position w/e. REFER TO THE PICTURE FOR THE ACTUAL QUESTION THANKS! (see the pic attached) My teacher taught me a method of seperating the LINE (ref.picture) into segments then calculating the area of each one then adding then up to get the final displacement but im wondering if my method will work. (not that I dont like her method but i dont find it to be of a sufficient accuracy due to human error.) Def of ellipse: An ellipse is a set of points in the plane, whose sum of distances from two fixed points is constant. I cannot draw a perfect ellipse i dont have graphing calculator so i can't derive the question of my answer from trying to get the sum of two points over and over again. Anybody?
