The chain rule (PDE)Im new on the forum, so I hope you guys will have some patience with me :-)
I have a question about the chain rule and partial differential equations that I cant solve, it's: Write the appropriate version of the chain rule for the derivative: ∂z/∂u if z=g(x,y), where y=f(x) and x=h(u,v) I have tried to do a dependence chart of it, but it's just not working for me. Thank you very much. |

Re: The chain rule (PDE)∂z/∂u=(∂z/∂x)(∂x/∂u)+(∂z/∂y)(dy/dx)(∂x/∂u)
Draw a diagram. It is pretty straightforward. |
