Homework Equations
The Attempt at a Solution
My question concerns the (1) and (2) next to the figure of the rotating coordinate system.
x=ucos(theta)-vsin(theta)
y=ucos(theta)...
...
So my problem is I can't visualize it. I can visualize that u = ucos(theta) + usin(theta), but I don't get how u = xcos(theta) + ysin(theta).
If anyone can explain or try to visually show it to me would be great. Thanks.
