[QUOTE="ChiralSuperfields, post: 6855263, member: 731016"] No worries! We all make algebra mistakes! Thank you for your reply [USER=700856]@erobz[/USER]! So, I'm just trying to understand how you got ## y\hat j = x\hat j##. I have drawn a grey square below. [ATTACH type="full" alt="1676496930323.png"]322331[/ATTACH] I'm trying not to use circular reasoning, but did you get ## y\hat j = x\hat j## because ##\vec r## will always form a right isosceles triangle since it is a square so ##\theta = 45##? Many thanks! [/QUOTE]
