Since the limit fails to exist along any line that passes through the origin with positive slope, the bivariate limit at the origin does not exist. Alternatively, access Maple's bivariate limit through the Context Panel.

Maple's declaration that the limit is undefined is equivalent to the more prevalent statement that the limit does not exist.
