### If the angle of a right triangle is equal to 30 degrees and then the value of cosine at this angle ie the value of Cos 30 degree is in a fraction form as 32.

Cosine of 30 degrees. The answer is as follows. In Sexagesimal angle measuring system the cosine of angle 30 degrees is written as cos 30. In trigonometry the cosine function is defined as the ratio of the adjacent side to the hypotenuse.

Posted by ecurtz at 800 AM on September 24 2010 Is it in degrees or radians. Sin 70 degrees cos 20 degrees. For cos For memorising cos 0 cos 30 cos 45 cos 60 and cos 90 Cos is the opposite of sin.

The sine of 30 degrees is 05 so the cosine is sqrt 075 since sine squared plus cosine squared equals one. It is noted that the value of Sec 30 will be reciprocal of Cos 30 value. The angles are calculated with respect to sin cos and tan functions.

Cos30 0866025403784 This is the same answer you will get if you have a scientific calculator set to DEG mode and then enter 30 followed by the Cos button. The sine of 35 degrees is 057358 rounded The cosine of 35 degrees is 081915 rounded. The angles are in degrees and multiples of 30 degreesSite.

Sine 3012 For angles less than a right angle trigonometric functions are commonly defined as the ratio of two sides of a right triangle. The value of cosine if angle of right triangle equals to 30 degrees is called cos of angle 30 degrees. The cosine of 30 degrees is 086.

It is also expressed as the square root of three divided by two. What is cos 30 degrees. Cos-1 Calculate Reset.

We should learn it like cos 0 sin 90 1 cos 30 sin 60 32 cos 45 sin 45 12 cos 60 sin 30 12 cos 90 sin 0 0 So for cos it will be like 1 32 12 12 0 For tan. The cosine of an angle is calculated by dividing the length of the side of a right triangle adjacent to the acute angle by the length of the hypotenuse. Below Table Values of sine cosine tangent cosec secant and cotangent at various degree of angles 0 30 45 60 90.

150 5π6- 3 2. π Calculate Reset. COSPI 6 Returns 0886.

This video will explain how to determine sine and cosine function value using the until circle. Every angle has a sine and a cosine. The sine of 35 degrees is 057358 rounded The cosine of 35 degrees is 081915 rounded.

Sine calculator Inverse cosine calculator. The cosine is a trigonometric function. The cosine of angle 30 degrees in the Sexagesimal angle measuring system is written or expressed as cos 30.

Here we answer one simple question. How to derive and memorize the trigonometric ratios of the special angles how to use the trig ratios of the special angles to find exact values of expressions involving sine cosine and tangent values of 0 30 45 60 and 90 degrees How to find sin cos tan cot csc and sec of the special angles and multiples of 90 How to remember special angles Grade 9 math with video lessons. Sin 60 degrees cos 30 degrees cos 60 degrees sin 30 degrees We will not do this computation but if we replace 30 degrees with 20 degrees and 60 degrees with 70 degrees you will find a similar result.

Usually the degrees are considered as 0 30 45 60 90 180 270 and 360. To find cos of another number please enter the number below and press Calculate Cos. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step-by-step explanations just like a math tutor.

The COS function returns the cosine of an angle provided in radians. 3 2 3 2 The result can be shown in multiple forms. If it is in degrees then it is sqrt 32 if it is in radians then carmichas answer.

Cos 30 32 In the fraction format the value of cos 30 is equal to 32. 135 3π4- 2 2. For example the cosine of PI 6 radians 30 returns the ratio 0866.

Use our cosx calculator to find the exact value of cosine of -30 degrees as a fraction or the cosine of any angle in degrees and in radians. Cos 30 cos 30 The exact value of cos30 cos 30 is 3 2 3 2. Cosine Tables Chart of the angle 0 to 90 for students.
