In mathematics, the cosine is a function of an angle. The cosine 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 sideadjacent to the angle divided by the length of the hypotenuse. The sideadjacent to an angle is the side that forms a right angle with the hypotenuse, while the hypotenuse is the longest side of a right triangle, the side opposite to the right angle.
In trigonometry, the triangulation of a circle, the cosine of an angle is the ratio of the length of the side opposite to the angle divided by the length of the hypotenuse.
The cosine of an angle can be calculated using the equation:
cos(θ) = opposite / hypotenuse
where θ is the angle in question, in radians.
In the case of a right triangle, the cosine of an angle is equal to the length of the sideadjacent to the angle divided by the length of the hypotenuse.
cos(60°) = adjacent / hypotenuse
plugging in the values from the figure above:
cos(60°) = 3.6 / 5
therefore, the cosine of 60 degrees is equal to 0.72.
What is the cosine of 60 degrees in radians?
The cosine of 60 degrees in radians can be calculated by using the equation cos(θ) = cos(60°) = 1/2. This means that the cosine of 60° is 1/2. To convert this to radians, we need to multiply by 2π, which gives us 1.57rad.

The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. In a right angled triangle, the cosine of the angle is equal to the length of the adjacent side divided by the length of the hypotenuse.
The cosine of 60° is therefore equal to the length of the adjacent side divided by the length of the hypotenuse.
In a right angled triangle, the length of the adjacent side is equal to the length of the hypotenuse multiplied by the cosine of the angle.
Therefore, in a right angled triangle, the cosine of 60° is equal to the length of the hypotenuse multiplied by the cosine of the angle.
The length of the hypotenuse is equal to the square root of the sum of the squares of the other two sides.
Therefore, the cosine of 60° is equal to the square root of the sum of the squares of the other two sides multiplied by the cosine of the angle.

Additionally, the cosine of 60 degrees is used in physics to help calculate things like wave interference and reflection. Without this value, many things would be much more difficult to calculate.
What is the cosine of 60 degrees in terms of the unit circle?
In mathematics, the unit circle is a circle with a radius of one that is centered at the origin of a coordinate system, usually the Cartesian coordinate system. The unit circle is often used to define the trigonometric functions, which are the basic functions of angle measurement.
The trigonometric functions are defined in terms of the angles that are formed when a straight line intersects the unit circle. The cosine function is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. In other words, the cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

Frequently Asked Questions
What is the value of cos0º and sin0º on a circle?
When we discussed the unit circle, we found that cosine and sine are the x- and y-coordinates of the points on the unit circle. What do these coordinates mean? When we find the value of cosine or sine for a given angle ϕ, the coordinates tell us how many degrees out from the vertical (y-axis) line that point is. For example, for an angle of 60°, cos60° = +1 and sin60° = -1. For θ = 90º, the x-coordinate is 1.5 and the y-coordinate is 0. Therefore, cos90º = 1.5, and sin90º = 0.
What is the value of cos 60 equal to?
The value of cos 60 is equal to 1.
What is the value of cos0º and sin0º?
The value of cos0º remains unchanged, and the value of sin0º becomes 1.
How do you find the value of sin in a circle?
First, y is negative since the radius point is towards the negative x-axis. So we subtract 1 from y to get cos(θ). Then we use sin() to find the sine value at that particular angle θ in radians (rad).
What is the value of Tan 0 in a circle?
There is no value for Tan 0 because it doesn't exist in a complete circle.
