The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). In fact, trigonometry is the study of relationships between the sides and angles of a triangle.
Trigonometric Ratios (T - Ratios) of an acute angle of a right triangle
In XOY-plane, let a revolving line OP starting from OX, trace out <XOP=q.
From P (x, y)draw PM ↓ to OX. In right angled triangle OMP. OM = x (Adjacent side); PM = y (opposite side); OP = r (hypotenuse).
* Remark 1 : sin q is read as the “sine of angle q” and it should never be interpreted as the product of ‘sin’ and ‘q’
* Remark 2 : Notation : (sin q) 2 is written as sin2 q (read “sin square q’’) Similarly (sin q) n is written as sinn q (read ‘‘sin nth power q’’ ), n being a positive integer.
* Note : (sin q) 2 should not be written as sin q2 or as sin2 q2
* Remark 3 : Trigonometric ratios depend only on the value of q and are independent of the lengths of the sides of the right angled triangle.
