Obtain the value of the wave function: (z)exp{- r/2} at the point P(3,3,-3). In your (formula) answer, use `sqrt()' for the square root function, and `exp()' for the exponential function.
You can use two asterisks, `**', or a caret, `^', to indicate powers, i.e., v^2 and v**2 both mean v squared.
Query, is the above answer correct?
