Partial Derivation with the TI-NSpire CX CAS

I am trying to perform a partial derivation with the TI-NSPIRE CX CAS. However, a variable is always output as 0 in the result.

Example with the nspire: d/dx(yx) = 0

But I would expect "y" as a result here.

Wolfram gives the expected result as example. How do I enter in the calculator that y is considered as a variable?

You forgot that there is no implicit multiplication. Use x*y not xy
