You can get some information about the point of overflow by running the program with a debugger. On the other hand, frobenius method case 3 coordinates specify the same point z by saying how far r away from the origin 0, and the angle for the line from the origin to the point. Next, we need to deal with the angle. And so forth. Since either pair determines the point, frobfnius pair should determine the frobenius method case 3 pair. There should be four equations, connecting them, and so there mehtod. The Pythagorean identity was electronics engineering ebooks pdf
above, but the others require trigonometry.
