Re: Minimising area of square and circle
If the answer is right I want all the credit. If not, anonimnystefy can take half the blame.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi amberzak
You are welcome.

Re: Minimising area of square and circle
Hi amberzak;
Thank you!
Next time before you run to calculus to solve the problem if you notice your original function is a parabola. There are easier means to find the maxima or minima of a parabola. Anyways, because it is a parabola in x the maximums will be at the endpoints 0 and L as indicated.
