Hello,

 

 

Lets say I have an equation y=mx^2. If I plot this equation in excel and then set the x-axis to plot in log is the same thing as y=m*log(x^2)?

 

Having difficulty in trying to discern what the log plot actually is doing.

No, you only transform the scale in a, well, logarithmic scale. First mark will range from 1 to 10 (but also logarithmic in between), 2nd mark from 10 to 100, etc. It does not do anything with your function itself.

The calculation has some difference.

y=mx²

log y = log m + 2 log x

axis Y ; log scale y

axis X; log scale x

you can obtain m value from the intercept.

 

To obtain m value from data, y var X² plot is more useful.

At this time we can obtain m value by using list square method of zero point intercept.
