Hello, guys. I wrote the code to a Quadratic Equations Solver and I'd like for you to run the program and read the source code and give me tips on what I can improve, what is good and what is bad, suggestions, etc. . #include <iostream> #include <locale.h> #include <math.h> …

do u have any code to find a system of two linear equations with two variables??

Hi.. d1 = a1*x1 + b1*x2 + c1*x3 d2 = a2*x1 + b2*x2 + c2*x3 d3 = a3*x1 + b3*x2 + c3*x3 Knowing all of a,b,c,d, I have to find x1, x2, x3. As you might noticed, this is high school math. But, how do I write the code to …

I am trying to solve a system of 5 equations in 5 unknowns. I am new to the Matlab language. I consulted the documentation and decided that the best way of doing this was to use the solve() function. However, this function does not appear to work properly for 5 …

Fairly new to php but know enough to be dangerous. I'm really stumped on this: I have stat numbers already in database linked with an id and also created an add stats page. So when a user is on the add stats page they enter the specific id & new …

i am currently working on creating mathematical models for my research and want a non linear equation solver library which i could integrate with my program . i searched the web and found op++ which wasnt a free program .
