QuadratQuadrat was my first program, and is also the best. I made it in Algebra II when my teacher told us that she would not accept decimal answers for quadratic equations. Since the calculator only does decimals, I set out to make a program that does radicals. Here it is. I used Quadrat every day when we did quadratic equations, and I still use it now. After I made it I didn't use the equations mode on the calculator since, because Quadrat does a much better job. To run it, put in the coefficents, then press EXE. In the top left corner of the screen is the radical answer, (with imaginary numbers, if need be). Below that are decimal solutions, if there are any. They are stored under G and H, as is written, so you can use them later in the run mode. A, B, and C are what you put in for the coefficents, so you know if you messed up or not. D is the deternimant. Note: If you put in decimals for the coefficients, you don't wont radical answers, so disregard the radical answer; it will be a big mess. The decimal G and H will still be right though. |
