Let Q = (0,5) and R = (10,6) be given points in the plane. We want to find the point P = (x,0) on the x axis such that the sum of distances PQ+PR is as small as possible.
To solve this problem, we need to minimize the following function of x: f(x) = ?
over the closed interval [A,B] where A = ? and B = ?
Thank you for your help, I really appreciate it...
But I am still not getting what the technique is here to answer the question.
I understand finding distance (d1) and distance (d2)
but the derivative part has me thrown off. Also, I don't get what function is supposed to be minimized...
How do I go step by step through this?
