How to do partial derivates?

So i have this function x*sin(x*y)

and I'd need to do a partial derivate like this with it: d^2/dxdy

How do I write it?

Answer 1

[Torsten]

syms x y
f = x*sin(x*y);
dxy = diff(diff(f,x),y)

dxy = 

dyx = diff(diff(f,y),x)

dyx = 

By the way: it's called "partial derivatives", not "partial derivates".
