Chain Rule and Total Derivatives
In this video, The idea of chain rule is defined from basic to advanced i.e function of one variable to function of two variable with complicated case which was asked in GRE Math test.
In calculus, the chain rule is a formula that expresses the derivative of the composition of two differentiable functions f and g in terms of the derivatives f and g. More precisely, if {\displaystyle h=f\circ g}{\displaystyle h=f\circ g} is the function such that {\displaystyle h(x)=f(g(x))}{\displaystyle h(x)=f(g(x))} for every x, then the chain rule is.
total derivative and chain rule are combined topic in advanced calculus of several variables and total derivative is depands upon how many independent variables we have. if you like the video than share it and support me with subscribe button.
