### Questions (8)

 14 Why is analysis called “analysis”? 12 Why do we believe the equation $ax+by+c=0$ represents a line? 4 Prove that $\lceil \frac{\sqrt{n^2+1+\sqrt{n^2}}}{\sqrt{n^2+3+\sqrt{n^2+2}}-\sqrt{n^2+2+\sqrt{n^2+1}}}\rceil = 2n^2+n+3$ 4 Are there numbers that if proven rational (or irrational) will have important consequences to mathematics? 3 Given $F:X \to X$ on $X$:Hilbert space satisfying some properties, prove that $F$ is surjective.
