Is it possible to do total derivatives (d/dx) instead of partial derivatives (∂/∂x)?

[sam_12156]

I could only find the partial derivative template and the diff() function but I want to know if its possible to return the total derivative.

For example
1. d/dx (3(x^2)+2y) = 6x +2dy/dx
2. ∂/∂x (3(x^2)+2y) = 6x

i'd like to be able to get the result of the first equation

For the diff function I entered diff(3(x^2)+2y,x) and it returned 3*2*x
