Default Good graphing packages/software?

Hi, I would like to know of some powerful free grahping packages. I want to plot equalities and formulas such as the ones in this attachment below- hard ones, ones that aren't in the f(x)=y form. Please let me know of any good grahping pacakges you know where I can plot such equations and formulas.
