Hi
why I have to add I in fz(z,zc)=uz+I*vz --> fz(z,zc,I)=uz+I*vz ?
to avoid error ?
var('x,y',domain='real')
var('z',domain='complex')
var('zc',domain='complex',latex_name=r'\overline{z}')
u(x,y)=x*y^2+y*x ;v(x,y)=x^2*y-y*x
fuv(x,y)=u(x,y)+I*v(x,y)
zDic={x:(z+zc)/2,y:(z-zc)/2}
uz(z,zc)=u.subs(zDic)
vz(z,zc)=v.subs(zDic)
show("uz : \t ", uz)
show("vz : \t ", vz)
fz(z,zc)=uz+vz
fz(z,zc)=uz+I*vz
#fz(z,zc,I)=uz+I*vz
