I am new to this subject:
- Cartesian, Cylindrical and Spherical coordinate system.
- Coordinate System Transformation
I have this example problem that I cant get the right answer.
Transform to cylindrical coordinates:
(a) $F=10ax -8ay +6az$ at point $P(10, -8, 6)$.
One of my problem is
- I dont know when to use the dot product or matrix transformation equation. Should I just solve for the cylindrical variables $(\rho,\phi,z)$ or use the dot product/matrix form to transform to another coordinate system?
I tried solving it using the equations but I cant get the correct answer. The correct answer is $12.81a\rho + 6az$
