Oh true haha forgot about those
Thank you!

You do need the error on the distance/angle for the x-axis error bars.

Okay so you're saying we didn't need to find the error on the angle at all? It was in the table in the short report, but if we don't use it for the error in the peak to peak voltage then why did we even need it?

The first one you mentioned is the only one you can use since you measured the voltage directly. If you were to assume that form and calculate the voltage from the given angle then you would have to consider the error on the angle.

For the error in Δ(Vpp(θ)/Vpp(0) ) are we to use the simple ΔVpp(θ) (ie the one from just the divisions in voltage) in our derivation? Or do you want us to also use Δθ by assuming that Vpp(θ)=Vpp(0)cos(θ) and then creating a new ΔVpp(θ) from that?

I used the simple one for my short report and didn't get any marks off but I wasn't sure if that's just because it wasn't checked as thoroughly.

Thanks!
