In geometry , curve sketching or curve tracing includes techniques that can be used to produce a rough idea of overall shape of a plane curve given its equation without computing the large numbers of points required for a detailed plot. It is an application of the theory of curves to find their main features. Basic techniques The following are usually easy to carry out and give important clues as to the shape of a curve Determine the x and y intercepts of the curve. The x intercepts are found by setting y equal to 0 in the equation of the curve and solving for x . Similarly, the y intercepts are found by setting x equal to 0 in the equation of the curve and solving for y Determine the symmetry of the curve. If the exponent of x is always even in the equation of the curve then the y axis is an axis of Reflection symmetry symmetry for the curve. Similarly, if the exponent of y is always even in the equation of the curve then the x axis is an axis of symmetry for the curve. If the sum of the degrees of x and y in each term is always even or always odd, then the curve is Rotational symmetry symmetric about the origin and the origin is called a center of the curve. Determine any bounds on the values of x and y . If the curve passes through the origin then determine the tangent lines there. For algebraic curves, this can be done by removing all but the terms of lowest order from the equation and solving. Similarly, removing all but the terms of highest order from the equation and solving gives the points where the curve meets the line at infinity . Determine the asymptote s of the curve. Also determine from which side the curve approaches the asymptotes and where the asymptotes intersect the curve. ref Hilton Chapter III 2 ref Newton s diagram Newton s diagram also known as Newton s parallelogram , after Isaac Newton is a technique for determining the shape of an algebraic curve close to and far away from the origin.

Unreferenced stub auto yes date December 2009 Other uses Stump disambiguation File Estompe.JPG thumb Stump A stump is a cylindrical drawing tool, usually made of soft paper that is tightly wound into a stick and sanded to a point at both ends. It is used by artists to smudge or blend marks made with charcoal , Cont crayon , pencil or other drawing media. By its use, gradations and half tones can be produced. Stumps are typically made of paper but can also be made of felt or leather . They are sold commercially in a range of sizes suitable for manipulations covering large areas, for operations on a miniature scale, and those in between. Technique When blending, a stump may be held at an angle to increase the surface area that contacts the paper. The tip of the stump must be kept clean while blending in light toned areas of a drawing, so as to not smear darker media from other areas onto it. Eventually the tool will become dull from use sandpaper pointers are often used to clean and re sharpen it. While similar effects can be produced by smudging with one s fingers, this deposits oil from the skin onto the drawing surface, making the surface less receptive to the charcoal or other drawing medium.
