 Mar 20 accepted Can a change of variable result in the evaluation of an integral in terms of elementary functions, whereas before the c.o.v. this was not possible? Feb 25 accepted Is this inequality for integrals correct: $\left|\int_{\mathbb{R}}\frac{f(x)}{g(x)}dx\right|>\left|\int_{\mathbb{R}}\frac{f(x)}{g(x)^2}dx\right|.$ Feb 24 accepted Does $\mid x-y\mid>0,x\neq-y$ imply $\mid\mid x\mid-\mid y\mid\mid>0$?
