I have 2 objects visible in the upload box which i wish to delete so as to come under my quota but can't for the life of me see how to delete.

Without a delete, I can't upload the graph I want to share.

Anyone browsing able to help?

Try deleting it here? If that doesn't work then tinyimage will let you upload it there and you can just link to it from here.

Hey guys,Try deleting it here? If that doesn't work then tinyimage will let you upload it there and you can just link to it from here.

I've taken Jameson wavy semi-circe and plotted inflection points on it (with some labour, got to tell you, as Geogebra found it beyond its brief to do it automatically) using perpendicular lines linking $f(x)$ with zeroed $f''(x)$

I've included it as a png screenshot from my pc, as I have been unsuccessful so far at uploading graphs or pics any other way.

Regs,

PS this is very much in the category of enthusiastic beginner of calc with time on his hands, in the middle of coming to terms with the meaning of second derivative.

$f(x)=\sqrt{30-x^2}+\frac{sin(x^2}{4}$What is the function?
