A limit can be a difficult concept to grasp in mathematics, as it is a value that is never reached, but is ‘approached’ by an input, or index of some…
read moreThere are several formulae and equations used for the interactions of straight lines. We will explore those below: Consider the equation (ax+by+c)(px+qy+r)=0 which is of second degree equation in two…
read moreThe polar form of a complex number a+ib is a+ib = r(Cos t + i Sin t), where r is its modulus and t is its argument. As we operate…
read morePerimeter of polygons: The perimeter of a polygon is the sum of all sides of its sides. i.e. the perimeter is the distance around the polygon. In the following figure,…
read moreIn vector product of vectors, the vector components are combined to give a vector. The vector product of two vectors is a vector which is perpendicular to both the given…
read moreEvery square matrix is associated with a real number which is called the determinant of the square matrix. Let S be the set of all square matrices and R be…
read moreIn scalar product of vectors, the vector components are combined to give a scalar. The scalar product of two vectors is the product of the component of one vector (in…
read moreTwo lines are said to be perpendicular if the angle between them is 90º (90 degrees). There is a result on perpendicular line which states: Two lines are perpendicular if…
read moreA number which is of the form a+ib, where a and b are real numbers and i2 =-1, is called a complex number and is usually denoted by z. i.e.…
