This booklet is the 1st of a multivolume sequence dedicated to an exposition of useful research tools in glossy mathematical physics. It describes the elemental rules of sensible research and is basically self-contained, even though there are occasional references to later volumes. we now have integrated a couple of functions once we notion that they'd offer motivation for the reader.

But busy as they are, most of my colleagues find the time to teach me, and they also trust me. Even though it was a bit hard at first, I can feel over time that I am beginning to be taken seriously and that my contribution is appreciated.

Thus z 3 = (x + i y)3 = x3 + 3i x2 y − 3xy 2 − i y 3 = x3 − 3xy 2 + i 3x2 y − y 3 , and z 2 = (x + i y)2 = x2 − y 2 + i · 2xy. It follows immediately that 3x2 y − y 3 = Re −i z 3 and i xy = Re − z 2 , 2 so u(x, y) = Re −i z 3 − i 2 z , 2 and we conclude that v(x, y) = Im −i z 3 − i 2 z 2 + c = −Re z 2 + 1 2 z 2 + c = −x3 + 3xy 2 − 1 2 1 2 x + y + c, 2 2 and f (z) = −i z 3 − i 2 z + i c, 2 c ∈ R. com 64 Complex Functions Examples c-3 Harmonic functions 2) Alternatively we conclude from Cauchy-Riemann’s equations that v(x, y) ∂u ∂u dx + dy ∂y ∂x − 3x2 − 3y 2 + x dx + (6xy + y)dy = c+ − = c+ −3x2 dx + 3y 2 dx − x dx + 6xy dy + y dy = c+ d −x3 + 3y 2 dx+3x d y 2 = c+ d −x3 + 3y 2 x − = −x3 + 3y 2 x − =c+ 1 1 − d x2 + d y 2 2 2 1 2 1 2 x + y 2 2 1 2 1 2 x + y + c, 2 2 c ∈ R, and f (z) = u + i v = 3x2 y − y 3 + xy + i −x3 + 3y 2 x − = −i x3 +3x2 (i y)+3x(i y)2 +(i y)3 − i 2 z + i c, 2 x2 −y 2 +2i xy +i c c ∈ R.
