HISTORY OF TRIGONOMETRY

THERE ARE 6 FUNTION OF AN ANGLE COMMONLY USED IN TRIGONOMETRY.

THERE NAMES AND ABBREVIATIONARENSINE(SIN),COSINE(COS

), TANGENT (TAN),cotangent(csc).There are 6 trigonometric function in

relation to a right triangle .

Trigonometric ratios They help us to find the missing

information of the right angled triangle.

The trigonometical ratios are sin ,cosine and tangent which can be found in scientific calculator .;sin ,cos and tan .
