good afternoon, please tell me how exactly on this calculator (casio fx 991ex) to solve two equations (intersection of a circle and a straight line), thanks.
On this calculator, if you are trying to solve a polynomial with a linear, it is a bit more difficult. You can't use Equation Solver menu since that only does simultaneous equations up to 4 unknowns, but not simultaneous polynomials. If you solve a polynomial it is looking only for the roots. One possible method would be to put both equations in y= and/or f(x)= form (so solve for y). The circle equation would then be a square root. You could then go to the Table menu and enter both equations (one in f(x), the other in g(x). Then find the intersections in the table. I would then use the QR code to 'see' the graphs and you could see the intersections. Of course, you are only going to see half the circle at a time, so you would need to do it again for the negative square root as well. A graphing calculator is a better tool for polynomial intersections.
Thanks for the help it made graphing and solving system of equations a lot easier :D
Thank you❤
How to do the cube root of 24 in the same calculator
I am solving simultaneous equations with decimal values, its giving me math error. But working on 991es plus calculator correctly.
