How to Draw a Parabolic Curve?
To draw a parabolic curve, divide the base width in half and mark the height of the parabola in the center. Extend a line segment from the base, through the vertex, to twice the height of the vertex. Draw segments from the end points on the base to the end of the line segment above the vertex, then divide those lines into any number of equal segments. Connect the first point up on the left to the last point up on the right, continue on in that fashion for all the points, and then do the same thing on the other side. You will end up with tangents to the parabola, which makes drawing the final curve easy! You can find more information at http://mysite.du.edu/~jcalvert/math/para…
