Then use the quadratic equation to find the largest value of m.
Hi, I was told that this was a simple calculus problem so I thought I should post it here.
What is the largest value of m such that the graph of the equation y=mx meets the graph of the equation (x-10)^2 + (y-5)^2 =4
Thanks for any help.
This isn't right. Applying the quadratic formula should give an expression only in terms of m (ie. no x's).(-444x-464mx)/(4x^2 +4m^2 x^2) and (-484x-484mx)/(4x^2 +4m^2 x^2)
See if you can get the discriminant the same as Mr Fantastic and follow his instructions from there.
