What is Parabola: If the intersecting plane is parallel to the generator of the cone but cut only one nappe is called parabola. We have already stated that a conic section is a parabola if . Here e is the eccentricity. We shall first derive an equation of a parabola in standard form and study […]

Quadratic Formula Derivation: Again there are some quadratic polynomials that are not factorable at all using integral coefficients. In such a case we can always find the solution of a quadratic equation by the quadratic formula. by applying a formula known as the quadratic formula. This formula is applicable for every quadratic equation. Derivation of

Angle in Math: Two rays with a common starting point form an angle. One of the rays of angle is called the initial side and the other is the terminal side. The angle is identified by showing the direction of rotation from the initial side to the terminal side.An angle is said to be positive/negative
