The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. The value of Cos 30 degree is √3/2 Another Different form of Cos 30° is cos pi/6 or cos π/6 Hence, cos pi/6 = √3/2 Cos 30° = √3/2 is an irrational number and it equals 0.8660254037 approx. And then, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric function of a particular angle. radians(value): This method converts the value passed to it from degrees to radians.

I was messing around with my calculator when in radian mode I entered the following $$\cos^{-1}\left(\cos(30)\right)$$ and it gave back $1.4159$. Basically, the digits of pi after $3$. Is this 2018-02-09 Introduction: When you delve deeper into your study of trigonometry, you will find that when talking about angle measures, the radian scale is much more widespread than the degree scale.Given this, it is imperative to know the important T-ratio values in the radian scale. These are summarized below (both degree and radian scales are used; when the angle value has no unit specified, it is Calculate cos(50)° Determine quadrant: Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positive. Determine angle type: 50 is an acute angle since it is less than 90° cos(50) = 0.64278761045041 Write cos(50) in terms of sin Important Angles: 30°, 45° and 60° You should try to remember sin, cos and tan for the angles 30 ° , 45 ° and 60 ° .

The answer is as follows: Cos(30) = 0.154251449888. This is the same answer you will get if you have a scientific calculator set to RAD mode andthen enter 30 followed by the Cos button. Use this simple cos calculator to calculate the cos value for 30° in radians / degrees. The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and calculate the exact cos 30° value easily.

Convert 30 degrees angle to radians: α (radians) = α (degrees) × π / 180° = 30° × 3.14159 / 180° = 0.5236 rad Degrees to radians conversion table Radians to degrees conversion ► Calculate the sin and cos of a value in radians (in one function)?
