Simple question as above. Given "A provided that B", the logical equivalence seems to be "A only if B". Very startling that my lecturer enjoy using such &...
I have the problem: Given that $g(x)$ is a quadratic function; that is in the form $g(x) = ax^2+bx+c$ for some constants $a,b,c$. Find the values of the c...
A sequence $\{a_n:n\in\mathbb{Z}_+\}\subset\{(0,\infty)$ is convex if $$ a_{n-1}+a_{n+1}-2a_n\geq0,\quad n\geq1 $$ This is equivalent to saying that $\{a_...
