If x^2+y^2=1, what is the largest possible value of |x|+|y|?
do you know calculus at all?
Just thinking about the graph in my head I would say the answer would be 2sqrt2
I am thinking of the point (sqrt2, sqrt2) on the circle
Do you mean (sqrt2/2, sqrt2/2)?
yes, thanks Coolstuff for picking that error up. :)
To maximize, x=y
so x=y=(sqrt2)/2
Therefore the answer is sqrt2
