Look to the Polyfitc output… it gives the coefficients for the various terms of the polynomial. Just create a polynomial function using these coefficients (you can even take them directly from the polyfitc output using their indices) and you get the actually polynomial.
@@PatJHeffernan Thanks...I will give it a try. I am new to Mathcad and curve fitting. I can create the polynomial but how do you determine the order ? This would make a great follow up video. ;0)
... and there I was, thinking this would get me into my polyester bell bottoms from the 70s. Nice work.
Too funny!! 🤪
can you tell me how to get the coefficients..
It's covered in the video starting at 3:00 (Polyfitc). Good luck.
Very informative. How can I get MathCad to provide the actual polynomial equation for the 3rd order example you are showing ?
