Cos 60

In Maththe Cosine function is one of the six fundamental functions of trigonometry. The adjacent side and hypotenuse are separated by an angle called the cosine, cos 60, this relationship is referred to as the cosine function.

Trigonometry is used to study the measurements of right-angled triangles that deals with the parameters such as length, height and angles of the triangle. It has an enormous application in the real world. Apart from Mathematics, it has a wide range of applications in various fields like engineering, architecture, medical imaging, satellite navigation, and the development of sound waves etc. Some applications use the wave pattern of trigonometric functions to produce sound and light waves. Consider the unit circle in the Cartesian plane. The Cartesian plane is divided into four quadrants. The value of cos 60 takes place in the first quadrant.

Cos 60

Therefore, we write it in the following form in trigonometry. The exact value of cos 60 degree can be derived using three methods explained below. To find the value of the cosine of angle 60 degrees, let us consider an equilateral triangle given below:. Let us consider the length of each side of the triangle as 2 units. Set compass to any length by a ruler. Here, the compass is set to 4. Finally, draw a perpendicular line on the horizontal line from point D, and it intersects the horizontal line at point E perpendicularly. Now, calculate the value of the cosine of 60 degrees and for this, measure the length of the adjacent side by a ruler. You will observe that the length of the adjacent side is 2. The length of the hypotenuse is taken as 4. Example 1. Explore Other Topics. Related Concepts. Trigonometry Table and Trigonometry Ratios. Sin Cos Tan Table.

In trigonometry, Sine, Cosine and Tangent are the three major or primary ratios, which are used to find the angles and length of the sides of the triangle. Cosine function defines a relation between the adjacent side and the hypotenuse of a right triangle with respect to the angle formed between the adjacent side and the hypotenuse. The trigonometric functions, sin, cos and tan for an angle are the primary functions. These trigonometric values are easy to memorize with the help trigonometry table. Now, to find the value of cos 60 degrees, let us consider, an equilateral triangle ABC as given below:.

Trignometric ratios of Specific Angles - Evaluating. Last updated at May 29, by Teachoo. Let's learn how. We will discuss what are different values of sin, cos, tan, cosec, sec, cot at 0, 30, 45, 60 and 90 degrees and how to memorise them. To learn the table, we should first know how sin cos tan are related. You can also practice questions by clicking Next.

Trigonometry is useful for studying the measurements of the right-angled triangles which deal with the parameters like height, length, and angles of a triangle. It has a variety of applications in the real world as well. Apart from Mathematics, it has a huge range of applications in several other fields like engineering, medical imaging, satellite navigation, architecture, development of sound waves, etc. Some applications make use of the wave pattern of the trigonometric functions to produce the light and sound waves. Trigonometry is a branch of Mathematics dealing with the right-angled triangles. This concept was initiated by the Greek Mathematician Hipparchus. It is further divided into plane Trigonometry and spherical Trigonometry. The cosine function in Trigonometry is used to find out adjacent sides or hypotenuses. Trigonometry is used in oceanography, meteorology, seismology, astronomy, physical sciences etc. It is also used to find out the height of tall structures and geographical features, length of a long river, upstream and downstream distance.
