Multivariable Calculus | Definition of partial derivatives.

We give the definition of the partial derivative of a function of more than one variable. In addition, we present some examples.

I think in the last example the partial d/dy should yield (x^3).(z^2)+2x? Love your channel Michael, cheers

At the time 12:00 11:59 more or less it's: d/dx (x^3*z^2 + 2x)
Which becomes 3x^2*z^2 +2

This is so true and can relate to it. Thanks a much

please, if f(a-z)=f(z)=0, z is Belongs to the complex plane and a is real constant , find
