Hey, im a bit confused oh how to use the chain rule when i have 2 variables in an equation...(adsbygoogle = window.adsbygoogle || []).push({});

Example : f(x,y) = (Squareroot(x)).(cosh(x+y^2)) x(s,t)=st y(s,t)=s/t

When i have 2 variables, im not sure how to split it up and use the chain rule, all the examples i found only have 1 variable :shy: Thanks :(
