Question

partial derivative G(s,t)=sqrt(st)/(s+t)

Answer 1

im doing it now. i dont think the chain rule applies to this one cus its not a funtion in a function. what do u think?

Answer 2

first or second partial derivative? respect to s, t or both?

Answer 3

first. \[G(s,t)=\frac{ \sqrt{st} }{ s+t }\]
this is not a function inside a function so you could use the Quotient rule and takethe derivatives with respect to s then with respect to t

Answer 4

\[G(s,t)=\frac{ (st)^{\frac{ 1 }{ 2 }} }{ s+t}\]
