Hi, I am currently working with Maple on school, and I wanted to use the diff(); function to find the partial derivative with respect to x. Anyways; I noticed when I was not using the multiplication sign I got the answer 0 as seen below:

diff(2*sqrt(xyz), x) = 0

But when I used the multiplication sign as seen (x*y*z instead), I got the correct answer.

diff(2*sqrt(x*y*z), x) = y*z/sqrt(x*y*z)

Why so?

 

Thanks,

Adrian
