vector has magnitude and direction. It start from one point to another point. The length of vector is called magnitude. The scalar product of two vectors is multiply and obtain a scalar quantity. It represent on ‘dot’. Another name is dot product. Vector and scalar product

circular measure
The radian is a unit of measurement angle . Therefore, this unit is used in many topics likewise sector , angles . Parts of the mathematics area which include circular measure and more often, the branch of angle measurements where pi (Π) is used. Therefore, radian use to measure arc length, chord length, area of sectors of a circle and many others. […]
Transformation
In this post question are from transformation of function. It basically deals with translation of functions through vector . Also it deal with reflection . Transformation
Co-ordinate geometry-1
Coordinate also called ordered pair. Hence manipulation of coordinate such as Determine the distance between these points. Find the equation, midpoint, and slope of the line segment. Determine if the given lines are perpendicular or parallel. Also deal with graphic representation. Coordinate geometry
Composite Function
Composite functions are defined as one function defined inside another function. Like ff(x)) or f(g(x)) etc. Another function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)) Composite function
Inverse of Function
Inverse of functions are an important concept . Domain values and Range values gets interchange . Due to these values of functions, continuity of function also change. Graph of inverse function also change and become y-axis oriented. Therefore graph of inverse is reflection of function graph about y = x. Inverse of function
Completing Square
Completing the Square is to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial. Completing the square is a technique for converting a quadratic polynomial of the form ax2 + bx + c to a(x-b)2+c. Hence this method is used to convert. Similarly […]
Quadratic inequality
A quadratic inequalities are degree is 2 and where the y is not always exactly equal to 0. A quadratic expression as either less than or greater than another number. Hence graph the solution set on a number line and/or express the solution using interval notation. Quadratic inequality
Combinations And Permutations
Combinations is a very important topic of mathematics as well as the quantitative aptitude section. In permutation we arrange object while in combination we select items. Combination and permutation
Binomial theorem
The expansion of two terms is know as Binomial theorems . Another way it is generalised form of expansion. Due to expansion of two term it is binomial. “What are the binomial coefficients?” . It shows how to calculate the coefficients in the expansion of (a + b) n. The symbol for a binomial coefficient nCr. As well as […]
