Calculus 3 Lecture 13.4: Finding Differentials of Multivariable Functions

Calculus 3 Lecture 13.4: Finding Differentials of Multivariable Functions: A review of Differentials from Calculus 1 and an extrapolation towards Differentials with more than 1 Independent Variable. Focus will be on the derivation of the idea of Differentials and the application of Differentials in Word Problems.
