Hi all, My first post...
I seem to be having trouble with solving for x in the following: sage: d = sqrt(x^2 + 5^2) sage: D = sqrt((20-x)^2 + 10^2) sage: T = d + D; T sqrt(x^2 + 25) + sqrt((x - 20)^2 + 100) sage: diff(T, x) (x - 20)/sqrt((x - 20)^2 + 100) + x/sqrt(x^2 + 25) sage: solve((x - 20)/sqrt((x - 20)^2 + 100) + x/sqrt(x^2 + 25) == 0, x) [x == 20*sqrt(x^2 + 25)/(sqrt(x^2 + 25) + sqrt(x^2 - 40*x + 500))] For some reason, Sage isn't solving completely for x, or isn't 'seeing' the x^2... Any help gladly appreciated!
