Domain of f(x,y)Can someone verify if this is the domain of def of the following function? "Fundamentally one will never be able to renounce abstraction." Werner Heisenberg #3 20060419 07:29:38
Re: Domain of f(x,y)Yes, (1y²)^{1/2}< x < (1y²)^{1/2} doesn't make sense, in the solutions guide, it's written : Last edited by Chemist (20060419 07:30:31) "Fundamentally one will never be able to renounce abstraction." Werner Heisenberg #4 20060428 09:20:18
Re: Domain of f(x,y)Hey, I've rechecked this : Plotting y=x , y=x would show that "Fundamentally one will never be able to renounce abstraction." Werner Heisenberg
