PROGRESSIONS AND SERIES

There are three progressions or series namely, Arithmetical Progression Geometrical Progression Harmonical These series are discussed below. ARITHMETICAL PROGRESSION (1)

COMPLEX NUMBERS

Complex number : A number of the form z = x + iy where x, y are the set of

VECTORS

Physical qantities are of two types: scalers and vectors. Scaler Quantity : Scaler quantities are those physical quantities which have

DETERMINANT AND MATRICS

Determinant : A determinant is shown by D. If we have a set of linear equations l1x + m1y =

INDICES

If x be any real number and n is the natural number, then xn = x C x C x

LINEAR PROGRAMMING

Linear Inequation with Two Variables : These inequations are written as ax + by > c, ax + by <

INEQUATION

Inequation : Inequation or inequality is a statement in which one thing is not equal to the other e.g. x

FUNCTION

Function : A function from X to Y is defined as a relation X C Y such that no two

QUADRATIC EQUATIONS

Quadratic Equation : A general quadratic equation is expressed as ax2 + bx + c = 0 where a ¹

LINEAR EQUATIONS

Equation : It is defined as a statement of equality which involves one or more variables. Linear equation : If
