Mar 11, 2021 ... After solving the elusive “Diophantine equation” for 42, MIT and U of Bristol mathematicians have discovered a new solution for 3. Given 3 points a(x1,y1), b(x2, y2), c(x3, y3) check if they form a non-degenerate triangle or not. If they do form a triangle then check if points p( ... x3 + y3 at (0, 0). 10). A) L(x,y) = 4 + 3x2 + 3y2. B) L(x,y) = 4. C) L(x,y) = 4 + x + y. D) L(x,y) = 4 + x3 + y3. 1. Page 2. 11) Find the tangent plane ...
