This calculus 3 video tutorial explains how to find first order partial derivatives of functions with two and three variables. Of z=(x^2)y, where x=t^2, y=t^3 using the change ru. In this video i will use the 1st 2nd partial derivative withrespectto x t to fi.
In this video i will show alternative notations of writing 1st 2nd partial derivative. In this video i will explain demonstrate another method (2) of using the chain rule t. In this video i will find the partial derivative withrespectto x y of f(x,y)=y^4+5x.
In this video i will explain another method (3) of finding the partial derivative z=f(. In this video i will find dz/dt=. In this video i will use the partial derivative to find max min of z=x^4+y^44xy+.
