I want to create a new function that I called HD to give a visual way to see the derivatives. For example:
The objective is apply the function HD[f_,x_]:
HD[f_, x_]
To obtain:
What I have at this moment is:
Format[HD[f_, x_]] := ("∂" f)/("∂" x)
But my result is:
In[41]:= HD[f, x]
Out[41]= f/x
What can be wrong?
