Hi,

On my HP-50G calculator, there are three ways to calculate the derivative (HP-50G differentiation tutorial):

- DERIV(function, variable)
- DERVX(function)

All of which can be used for symbolic differentiation. With the partial derivative, isn't that basically a fancy way of denoting differentiation in higher dimensions (just so it isn't confused with 1D derivatives symbolically)? So even though I use the partial derivative for simple calculations, which would be represented as on my HP-50G calculator, it still is a typical derivative because it is operating at a single-variable level?

Thanks in advance.
