General formula
Thanks for any help.
 I'm having a hard time trying to understand how come ∂r^/∂Φ = Φ^ ,∂Φ/∂Φ = r^ > these 2 are properties that lead to general formula.
 I've been thinking about it and I couldn't explain it. I understand every step of "how to get Divergence of a vector function in Cylindrical Coordinates" except for these formulas below.
