You can solve this system of linear equations using WolframAlpha
Hi guys,
I've been presented with a maths puzzle/equation to solve, but after some searching and an attempt at a self taught crash course I've still not been able to find a solution to this problem. So could anyone solve this please.
I need to find the approx values of a-f in this equation.
y = ax^5 - bx^4 + cx^3 - dx^2 + ex - f
Where x and y are....
x y
-15 -5,439,067
-10 -726,897
-5 -24,127
5 21,213
10 685,283
15 5,232953
If anyone could solve this that would be great thanyou.
Barry

Hi thanks for the link, but unless I'm missing something (and I literally have no idea at all) but I don't think that could work out non linear regression equations (not that I know exactly what that means but I think I get the gist). There's no-where to put parameters in. Or am I wrong?
