Trigonometric Ratios Table 0 30 45 60 90 Degreeођ Trigonometric ratios table helps to find the values of trigonometric standard angles such as 0°, 30°, 45°, 60° and 90°. it consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. these ratios can be written in short as sin, cos, tan, cosec, sec and cot. the values of trigonometric ratios of standard angles. The values of trigonometric ratios for the angles 0°, 30°, 45°, 60°, and 90° in a trigonometry table are commonly used to solve trigonometry problems. these values are associated with the measurement of the lengths and the angles of a right angle triangle. thus, 0°, 30°, 45°, 60°, and 90° are called the standard angles in trigonometry. I have noticed that students cannot actually remember values of six trigonometric ratios (sin, cos, tan, cosec, sec and cot) for 0. , 30. , 45. , 60. and 90. these values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked. there is a proper method to memorize all. Cos 45° = 1. cos 60° = √ (1 4) = 1 2. cos 90° = √ (0 4) = 0. since, we know the sin and cos value of the standard angles from the trigonometrical ratios table; therefore we can easily find the values of the other trigonometrical ratios of the standard angles. the tangent of the standard angles 0°, 30°, 45°, 60° and 90°: tan 0° = 0.

The table provided in this section will help you to find the values of trigonometric ratios for the special angles 0°, 30°, 45°, 60° and 90°. the values of trigonometric ratios of some special angles are very important to solve many problems in trigonometry. therefore, it is important to remember the values of the trigonometric ratios of. Trigonometric ratios table. the trigonometric ratios table displays the values of trigonometric ratios for the standard angles 0°, 30°, 45°, 60°, and 90° used in several trigonometric calculations.
