Trigonometric ratios provide relationships between the sides and angles of a right angle triangle. The three most commonly used ratios are: = RECIPROCAL RATIOS. To get the reciprocal of a number, just divide 1 by the number. Example: the reciprocal of 2 is 1/2 (half) Every number has a reciprocal except 0 (1/0 is undefined)
Trigonometric Ratios. For a right angle triangle, the relationship between lengths of sides and angles is described using the trigonometric ratios. . The 3 primary trigonometric ratios are: sine (sin), cosine (cos) and tangent (tan). For a given angle, A, the primary trig ratios are defined as follows: Sin(A) = hypotenuse.
