 Oct24 comment Nature of the range of $e^x$ All transcendental numbers are irrational, so I'm not sure what the role of the "or" is here. Did you mean to ask if $e^x$ is transcendental whenever $x\ne\log{a}$ for some $a\in\mathbb{Q}$? Oct24 comment Finding the co-ordinate vector You seem to have swapped the roles of $x_1,x_2,x_3,x_4$ and $d,c,b,a$ from the question, which is maybe a little confusing! Oct24 comment Finding the co-ordinate vector I think you might have a typo (or a confusion) in the last line as well - the solution is finding $x_1,x_2,x_3,x_4$, not $a,b,c,d$, which are arbitrary real numbers. Oct24 answered Finding the co-ordinate vector Oct24 comment Finding the co-ordinate vector I don't think you meant for $v$ to be what you wrote - perhaps $v=a+bt+ct^2+dt^3$?

A graph is $n$-connected if you can delete any \$k
