With trigonometry we can find the height of a building or the width of a river without actually climbing or crossing. Certain basic definitions are necessary to further develop this subject. The ratios of two sides of a triangle are taken. There are six possible combinations. Ea..

A function f(x) is called periodic if there exists a non zero number p such that f(x+p) is defined and f (x+p) = f(x) for all values of x in the domain of f(x). The number p is called the period of f(x). The function sinx has periods 2 p , 4 p ,6 p ,....since sin (x+2..

As x increases from 0 o to 90 o cosx decreases from 1 to 0, as x increases from 90 o to 180 o cosx decreases from 0 to -1, as x increases from 180 o to 270 o cosx increases from -1 to 0, as x increases from 270 o to 360 o cosx increases from 0 to 1. Cosx is period and has a ..

The circular functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equiva..

From the graph it is clear that the curve repeats itself every 360 o (2 p rad). This fact is expressed by the statement that the function has a period of 360 o (2 p radians). In symbols we write cos(x + 360 o .n) = cos(x + 2 p n) = cos x where n is a positive or negative integer. Fr..
