Hi
I'm working on some questions and I'm just unsure how one of the solutions work.
I'm given
x=1/2(u^2-v^2)
y=uv
z=z
and in the solution it is transformed into
u=[x+(x^2+y^2)^1/2]^1/2
v=[-x+(x^2+y^2)^1/2]^1/2
z=z
I'm unsure how it was transformed. The question says to use "inverse transformation" but I'm not sure what that is.
Thanks!
