I am quite new to the topic of multivariable calculus. I came across the concept of "gradient" (∇), and although the treatment was somewhat slapdash, I think I got the hang of it. Consider the following case:
##z = f(x,y,t)##
##∇z = \frac{∂z}{∂t} + \frac{∂z}{∂y} + \frac{∂z}{∂x}##
If we're dealing with a physical scenario, wherein the variables x, y and t have different units, how is it possible to compute ∇z?
##z = f(x,y,t)##
##∇z = \frac{∂z}{∂t} + \frac{∂z}{∂y} + \frac{∂z}{∂x}##
