Hi tony123;

**In mathematics, you don't understand things. You just get used to them.I have the result, but I do not yet know how to get it.All physicists, and a good many quite respectable mathematicians are contemptuous about proof.**

You can substitute this back in (2) and also make (say) x the subject, and hence get an equation in y.
