Hi,

Struggling slightly with drawing a phasor diagram as it's not been taught to us very well.

Asinwt
Bsinwt +pi/2
A=10
B=5
w=1000pi
t=0

This is all they've given us and I've plotted the graphs on Excel but it asks for the following: Plot the phasor diagrams to find the peak voltages for the sum and difference of the waveforms.

And when I said struggling slightly I mean struggling a lot with where to start....
Any help appreciated

 

My bad....
t=0 to 5 milliseconds

 

Okay, so what does your best attempt at a plot of the phasors and their sum/differences look like. What do the graphs you plotted using Excel look like? We aren't mind readers.

 

I think your transcription might be a bit sloppy. Did you mean:

\(B sin(\omega t + \frac{\pi}{2})\)

or something else?

These might help

Sorry I was posting off my phone so couldn't post the equation in the correct form. Using excel I created a formula page and a data page then a scatter diagram using the data. Using the formulas given I had to create two phasor diagrams one of the sum and one of the difference.
I figured it out and drew the two phasors so this thread can be closed, thanks anyway.
