**∂**notation and the

**d**notation. For example, on http://tutorial.math.lamar.edu/Classes/CalcIII/ChainRule.aspx, in Case 1, the author wrote dz/dt while in Case 2, the author wrote ∂z/∂t. Could anyone please explain to me when I should use the

**∂**notation and the

**d**notation.

Any help is much appreciated. Thanks a lot...
