Any point P with coordinates (\(x, y\)) on the circumference of a circle can be joined to the centre (0, 0) by a straight line that forms the hypotenuse of a right angle triangle with sides of length ...

If a quadratic equation can be factorised, the factors can be used to find the roots of the equation. The equation factorises to give \((x + 3) (x - 2) = 0 \) so the solutions to the equation \(x^2 + ...

Experts claimed today they had discovered the scientific formula for taking the perfect penalty. The formula, (((X + Y + S) / 2) x ((T + I + 2B) / 4)) + (V/2) -1, was developed by scientists at John ...
