Trigonometric Angles :
Table Values of sin, cos, tan, cosec, sec and cot at various degree of angles
(0°, 30°, 45°, 60°, 90°, 180°, 270°). Trigonometry is also spelled as Trignometry.

Trigonometric ratio / function:
The formulae (formula) for finding angle and sides of triangle can be easily remembered using the
sentence - "Old Harry And His Old Aunt".
Sin (q) = Old/Harry = Opposite/Hypotenuse
Cos (q) = And/His = Adjacent/Hypotenuse
Tan (q) = Old/Aunt = Opposite/Adjacent
Trigonometric table (values) of sine, cosine, tan, sec, cosec, cot values at different angles and Basic Formula and function of trignometry ratios.
