Cos 30 deg

The value of cos 30 degrees is 0. In this article, we will discuss the methods to find the value of cos 30 degrees with examples.

In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i. It is noted that the value of Sec 30 will be reciprocal of Cos 30 value. Knowing the property that length of an opposite side is half of the length of the hypotenuse — Right triangle property for an angle equal to 30 degrees in the given right triangle. As we know two sides those are the length of the opposite side and hypotenuse but the third side is unknown i. We need to find this side to find the value of Cos 30 degrees. We will use the Pythagorean theorem to find the value of this third side.

The important trigonometric angles are 0, 30, 45, 60, 90, , and The angles for six trigonometric functions like sine, cosine, tangent, cosecant, secant and cotangent can be found easily. The value of cos 30 degrees in decimals is 0. We know that the angle of 30 degrees takes place in the first quadrant of the Cartesian plane; the value of cos 30 degrees should be a positive value. From the trigonometry table, some degree values of sine functions and cosine functions are used to find the value of cos The trigonometric ratios for different angles and functions are:.

In a right-angled triangle, cosine is the ratio of the base and hypotenuse. The value of cos 30 degrees in decimals is 0. In order to find the value of cos 30 degrees, the unit circle is taken into account. The methods are mentioned below:. Trigonometric functions are also called circular functions or trigonometric ratios. The relationship between angles and sides is represented by these trigonometric functions.

In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i. It is noted that the value of Sec 30 will be reciprocal of Cos 30 value. Knowing the property that length of an opposite side is half of the length of the hypotenuse — Right triangle property for an angle equal to 30 degrees in the given right triangle. As we know two sides those are the length of the opposite side and hypotenuse but the third side is unknown i. We need to find this side to find the value of Cos 30 degrees. We will use the Pythagorean theorem to find the value of this third side. Another way to calculate the value of Cos 30 degree is through a practical approach. Step 2: With the help of a protractor makes an angle of 30 0 with the centre as P and taking the baseline as the drawn line in step 1.

While trigonometric tables contain many approximate values, the exact values for certain angles can be expressed by a combination of arithmetic operations and square roots. The angles with trigonometric values that are expressible in this way are exactly those that can be constructed with a compass and straight edge , and the values are called constructible numbers. For angles outside of this range, trigonometric values can be found by applying reflection and shift identities such as.
