16	Is there a step by step checklist to check if a multivariable limit exists and find its value?
9	Check my workings: Prove the limit $\lim\limits_{x\to -2} (3x^2+4x-2)=2 $ using the $\epsilon,\delta$ definition.
4	Is there a faster way to do this? Find an orthogonal matrix $P$ and a diagonal matrix $D$ such that $A=PDP^T$
4	Is this proof correct? To prove $F(A)\cap F(B)\subseteq F(A\cap B) $ for all functions $F$.
4	Evaluate the following integral, $\int\sqrt{4-\sqrt{x}}dx$
