## Main Question or Discussion Point

I derived a relationship between frequency and tension of a string, accounting for tension's effect in the linear density of the string.

So in a nutshell, the equation is more complicated and is in the form of

f^2=aT^2+bT (f is frequency, T is tension, ab are constants involving the control variables which I would know from another experiment).

If I graph T against f^2 with collected data, I would get a quadratic line of best fit. I am so used to modifying the data to show a linear relationship in my high school physics class, but this data is impossible to modify to be linear. I want to obtain the percent error of the constants a and b to suggest the validity of the equation. Is this a reasonable scientific argument?
