Conic Section Solver Enter the equation to the program like so: 4x^2 + 16x + 9y^2 - 54y = -61 Coefficients: goes in like so x^2: [enter here] 4 x: [enter here] 16 y^2: [enter here] 9 y: [enter here] -54 num on other side of eq num: [enter here] (make sure this number, -61 without a variable, is on the other side of the equals sign, not the side where the rest of all those variables are) Uses very complex (nice explanation, huh?) math to solve out standard form conic sections. Equations in the form of ax^2+bx+cy^2+dy=e can be transferred into their regular form equations, like this: 4x^2 + 16x + 9y^2 - 54y = -61 to this (x+2)^2 (y-3)^2 -------- + ------- 9 4 This may not seem like a lot of work, but to transfer this took some serious math, and we know that when it comes to serious math, thats what calcuators are for, they can do it for us. If the 4 above was negative, my program would display it with a minus sign instead of the plus like this: (x+2)^2 (y-3)^2 --------- - -------- 9 4 cuz thats what would happen if that were the case. It can also switch the equation around if the 9 in the equation above were negative, and switch the 4 back to being a positive, then to display it like this: (y-3)^2 (x+2)^2 -------- - --------- 4 9 All equations given are equal to 1, so make sure you know that. It wouldn't be much of an equation without an equals sign, so its there, i just didnt have room. It also tells you what type of conic section it is. Unfortunately, it cannot handle parabolas, they are too hard. A new version will come out very soon with the parabolas in it, so look for it.

Thanks for downloading this, have an interesting day.
