Homework Statement
Prove that the straight line x cos @ + y sin @ = p is a tangent to the ellipse x2/a2 + y2/b2 if a2 cos2@ + b2 sin2@ =p2 .
u and v are the perpendicular distances of a tangent from the two points M(0,ae) and N(0,-ae) respectively. Prove that u2 + v2 is a constant...
Please correct me where I'm wrong,
Our solar system is moving around our galaxy at 250km/s and CERN can accelerate a particle to 99.99% the speed of light. If you are observing a particle going 99.99% of c from outside our galaxy and it happens to be moving the same direction of our solar...
