If a tangent line is drawn to the parabola y = 3  x^2 at any point on the curve in the first quadrant, a triangle is formed with the axes. At what point on the curve should the tangent be drawn to form a triangle of least area?

Reiny,
In the following question and in my reply the only difference was that the equation was
y = 4 x^2 instead of your y = 3x^2
Just make the appropriate changes.
