Consider the conic ex^2 + y^2 2e^2x 2^2y + e^3 + 3 = e. Suppose P is any point on the conic and S1, S2 are the foci of the conic, then the maximum value of (PS1 + PS2) is
Language is remarkable, except under the extreme constraints of mathematics and logic, it never can talk only about what it's supposed to talk about but is always spreading around.
