Mathematically modeling a real system in C#

[BvU]

Can we see something of the results ?

This is a fit that I did today. And it fit the data that I measure. it is off at little as you do down. and I think it is because I did not iterate it. I think to iterated it , I would have to solute for A B and w again . I just do not know when to stop.

You should adjust the vertical scale on your graph. What you show here looks like nothing more than a horizontal line, $y \approx 100$.

I have been trying... but the graphing calculator does not let me... it is very frustrating, I am only using it because it comes with my computer .

Try desmos instead.

Two other options for graphing:

This one is really a downloadable emulator; not an online calculator $=$

GeoGebra, available at https://geogebra.org, can be used online, and can be downloaded for offline use, including a downloadable graphing calculator.

It looks like you are using the Windows Calculator to do the graphs.
Click the icon circled below to open the Graph Options dialog.

On the Graph Options dialog, you can change the scale on the x-axis or the y-axis, change the units (radians, degrees, or grads), or change the line thickness.

You'll get a more useful graph by changing the limits on the y-axis to better show the oscillation.
