  • Absolute Value

      The Absolute Value ( or modulus ) of a number is the distance of a number from its origin. In other ways absolute value of a real number ‘a’ is numerical value of ‘a’ without regarding its sign.The absolute value of 3 is 3 .The absolute value of -2 is 2.The notataion... read more...

  • Acceleration

    Acceleration is the rate of change of velocity. In one dimensional motion acceleration is rate at which something speed up or slow down its motion. Since velocity is a vector quantity, acceleration is rate of change of both magnitude and direction of velocity.Accelaration has the dimension L / T2 ,... read more...

  • Accuracy

     Accuracy of a measurement system is the degree of closeness of  measurements of a quantity to that quantity’s actual value. The precision of a measurement system is the degree to which repeated measurements under unchanged conditions show the same result.If the measurement system... read more...

  • Acre

    Acre is a unit of area in different systems. The most commonly used acre today is International acre. One International acre is equal to 4046.8564224 square meters. The acre is related to square mile.1 square mile is 640 acres and 1 mile is 5280 feet ( 1760 yards ). One acre comprises 4,840 square... read more...

  • Addend

     A number which participates in addition. Numbers being added are considered to be addend.In the example given below2 + 3 = 5; Here 2, 3 are considered to be addends.A + B = C; Here A, B are called addends.  read more...

  • Adjacent Angles

    Two angles are said to be adjacent, if they have common side and common vertex and don't overlap. A pair of angles is if sum of their measures is 90 degree. A pair of angles is supplementary, if sum of their measures is 180 degree. read more...

  • Algebraic Equations / Polynomial Equations

     In mathematics algebraic equation also called polynomial equations over a given field is an equation of the form P=Q, where P and Q are polynomials over that field. X2 + X*Y - 5  =  Y5 + XY3 - 4  is an algebraic equation over the field. Two equations are said to be... read more...

  • SETS and Types of SETS

    The Basic idea of a set was first introduced by Georg Cantor. A set is a well defined collection of distinct objects. Thus a set is determined, Whether the given object is belongs to or does not belong to the set. Let us show some example.(1) Even natural numbers less than 20, i.e., 2, 4, 6,... read more...

  • Stationary Points

    In mathematical calculus, stationary point is an input to a function where the first derivative of a function or slope of function is zero( i.e., dy / dx = 0 ). dy / dx called derivative of y or slope of the function y = f( x ). In stationary point function stops increasing or decreasing. A... read more...
