- Homework Statement
- I try to derive coordinates for a mass on a rotating pendulum using a different coordinate system

- Relevant Equations
- $$(x,y)$$

For this problem,

I correctly got the same coordinates for the pendulum mass using another coordinate system. The coordinate system I used was the other coordinate system rotated counterclockwise by 90 degrees. Why is the pendulum mass coordinates invariant in my cartesian coordinate system (x̄,ȳ)?

Thanks for any help!
