PolynomialsEngineering expressions often take the form The following is based on a cue card that can be processed directly in any word processor, using MATHSERV. For example: FX = "A + B*X^2*exp(C*X) = 0" where **** A = 2 **** B = -1 **** C = -.385 You would enter in the f(x) box: 2-x*x*exp(-.385*x) -2 for xmin, 11 for xmax, and -2 and 2 for y and .00001 for tolerance. Second example: FX = "A + B*X + C*X^2 + D*X^3 + E*X^4 = 0" where **** A = 1 **** B = -32 **** C = 160 **** D = -256 **** E = 128 You would enter in the f(x) box: 1-32*x+160*x*x-256*x*x*x+128*x*x*x*x 0 for xmin, 1 for xmax, and -1 and 1 for y. |
