The input values appear within the parentheses throughout the above table. 28 May 2002 If the angle is in degrees you must first convert it to radians. There are two Those that you will use most often are displayed in the table below. Note that the SIN(RADIANS(30)) equals 0.5, the sine of 30°. cosine: cos(q) Students define sine and cosine as functions for degrees of rotation of the ray formed by the Students use special triangles to geometrically determine the values of sine and cosine for 30, 45, 60, and Place a chart at the front of the room. 7 Feb 2020 Trigonometry Table: Check out the Trigonometric Ratio Table, values of trigonometric Sine, cosine, tangent, cotangent, secant and cosecant are the six trigonometric ratios. Angles in Degrees, 0°, 30°, 45°, 60°, 90°. 13 Jul 2014 A poster with a table of exact values for sin, cos and tan at 0, 30, 45, 60 and 90 degrees. This could be useful for young people doing higher

## Students define sine and cosine as functions for degrees of rotation of the ray formed by the Students use special triangles to geometrically determine the values of sine and cosine for 30, 45, 60, and Place a chart at the front of the room.

The angles are calculated with respect to sin, cos and tan functions. Usually, the degrees are considered as 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°. Here, we will discuss the value for sin 30 degrees and how to derive the sin 30 value using other degrees or radians. Chart with the sine, cosine, tangent value for each degree in the first quadrant Important Angles: 30 °, 45 ° and 60 °. You should try to remember sin, cos and tan for the angles 30 °, 45 ° and 60 °. Yes, yes, it is a pain to have to remember things, but it will make life easier when you know them, not just in exams, but other times when you need to do quick estimates, etc. Sine, is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (which divided by) the length of the longest side of the triangle (thatis called the hypotenuse).

### Table values of cosine, sinus, tangent of 30 degrees and explanation of how these values are calculated with numbers and formulas.
