Hi, Is the answer: y(x) _homogenous =v(x) y(x) _private =u(x)v(x) ? Or they refer to something else? I don't know how to approach to it

\[ if: w=w(x,y), and: w=u+iv, then: u==x, v==y, then, w=x+iy (??) \] \[ \delta w=w(x+\delta x, y+\delta y) - w(x, y)=\delta x +i\delta y \] \[ \delta z(\partial w/\partial z)+\delta z^*(\partial w/\partial z^*) =\delta (x+iy)* 0.5*(\partial w/\partial x+i*\partial w/\partial y)+\delta (x-iy)*...

I know it is NOT A MULTIPLICATION, I know what "delta" means... I don't know how to prove that equation (17)

Hi, I have this problem and its solution but i know what right size is, but i don't understand what left size (delta*w(z, z)) is equal to
