comment Evaluating $\int\sqrt{150^2-x^2} \cdot dx$
yes i do understand that, i just wanted the OP to know what really was going on. By the way, your answer, though neat, does lack a bit of description. It would've been better if you had elaborated a bit more. Maybe you had no time whilst writing down the answer but still, it would have avoided discussions like ours :)

comment Evaluating $\int\sqrt{150^2-x^2} \cdot dx$
It's the same thing if you do it this way or by directly substituting $ x = 150sint $. In fact, the method you suggested is just an un-required step into getting the same answer. Say you replaced $x$ with $150\cdot y$. Then you'd get something like $\sqrt{150^2-150^2\cdot y^2} = 150\sqrt{1-y^2}$. You then end up at the same place where Clive started. Hope it helps! Cheers

comment Why does the Dedekind Cut work well enough to define the Reals?
Thank you for a more rigorous proof. I think I need to get used to such rigor in my mathematics(as opposed to the "less rigorous" mathematics at high school) , and this was very helpful. Thank you. I hope I am not rushing into things but I am enjoying my ride so far :)
