Simple proof of a basic chain rule for partial derivatives. The notion of differentiability is incorporated into the proof. Such ideas have lots of applications in university mathematics.
Would you do a proof of the chain rule involving two intermediary variables each depending on two independent variables? For instance, let w be a differentiable function of x and y, and let x and y be differentiable functions of r and s. The only explanations I can find involve tree diagrams, and that seems to hand-wavey.
Thanks. Glad you found it helpful.
Thanks!!!!! This was quite helpful
Thanks for the video explanation!!
awesome sauce
thanks
How to differentiate w with respect to x? x=g(r,s)
You didn't define the domain and co-domain. Could you please do that
An example would be R and R^2 👍
Wow you really replied after 11 years.
So, since R^2 = C this proof also holds for komplex functions, right?
