Rational and Reciprocal functions

A rational functions is a function of the form f(x)=p(x)/q(x), where p(x) and  q(x) are polynomials and q(x)≠0 ,q(x)≠0 . The domain of a rational function consists of all the real numbers x=0 except those for which the denominator is x= 0 . reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.. The […]

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. […]

Double angle Identity

Double‐Angle and Half‐Angle Identities. Because sin x is positive, angle x must be in the first or second quadrant. The sign of cos 2 x will depend on the size of angle x. A double–angle function is written, for example, as sin 2θ, cos 2α, or tan 2x, where 2θ, 2α, and 2x are the angle measures and the assumption is that you […]

Sequences and series

Sequences are useful in a number of mathematical disciplines due to,  for studying functions, spaces. Mathematical structures using the convergence properties of sequences. In particular, sequences are the basic for series, which are important in differential equations and analysis.   sequence and series

Function and Equation

Function notations are method of writing equation. Mostly , functions are portrayed as a set of x/y coordinates. Therefore   y-axis serving as a function of x. When we use function F(x) notation then one is  independent variable and another  dependent variable. Due to this on Y-axis F(x) represent. Function notation
