Clone of Algebraic Expression Calculator

## Deliverables Simplified Clone of Algebrator: ______________________________________________________ I would prefer that it be programmed in Visual Basic instead of Delphi or Java. I believe Visual [login to view URL] is powerful, but I'm concerned development will slow needlessly. The calculations must be accurate. The program must no the proper order calculations are performed. Insider paranthesis first and such. People must be allowed to enter whatever variables they wish. If they want to use X, Y, Z they can. If they want to use A, B, C for variable they can. If they want to use A, Y, C they can. If they want to use one variable they can if they want to use 15 variables they can. A, AB, AX, B, C, E, G, H, I, K, L I would like a clone of this algebra expession calculator. For example (x-3)(x+6)= x^2+ 3x-18 I would like a clone of this program. I don't want the Math Work Sheet Builder. I have a scientific calculator which I want to use in conjunction with the algebraic calculator. I would like the step by step display of calculation. However I don't think I can offer the explanation for steps I don't understand offered by the SoftMath. [login to view URL] Algebrator can solve problems in the following areas: arithmetics ______________________________________________________________________ 1. simplification of algebraic expressions operations with polynomials, exponential expressions, fractions and radicals (roots))complex numbers. 2. solving linear, quadratic and other equations and inequalities solving a system of equations. 3. graphing (lines, parabolas, hyperbolas, circles, ellipses, equation and inequality solutions). __________________________________________________________________________________________________________________________________________ The following items not developed from the original cloned. *************unlimited drill-and-practice problem and exam generation hundreds of pre-entered problems supplied _____________________________________________________ Testing the program is easy just plug in whole numbers other than zero and see if the answer = the answer which would be true. (x-3)(x+6)= x^2 + 3x-18 If x=10 (10-3) * (10+6)= 112 (7) * (16) If x=10 x^2 + 3x - 18 10^2-3(10)-18 = 112 100+ 30-18 The program must be able to calculate sine, Cosine, tangient) For example (x-3(cos(15))) * (x + 6(sin(15))) Sine, Cosine, Tangient Keys are already included in the scientific calculator. It also needs to calculate square roots (x+3(square root(9)) The calculation is provided with the calculator The calc will need 2d X, Y graphing and 3d X, Y, Z graphing. A graph for each calculation off to the side would be helpful. +100 to -100 for the X Axis and +100 to -100 for the Y Axis +100 to -100 for the Z Axis. Crystal Reports will probably need to be used. A small graph and if they desire a bigger graph full screen if they clicked on a button which navigated to a bigger graph. They must be able to get back where they started. 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows XP, 2000, 98, ME
