Cosine of angle calculator

A corner is a geometric figure formed by two rays (sides of an angle) coming from one point (which is called the vertex of the angle). A plane containing both sides of an angle is divided by an angle into two areas. Each of these areas, combined with the sides of the corner, is called a flat angle (or simply an angle, if this does not cause discrepancies). One of the flat corners (usually the smaller of the two) is sometimes conventionally called internal, and the other external. Points of a flat angle that do not belong to its sides form the inner region of the flat angle.

Our cosine of angle calculator makes it easy for you to find the cosine of any angle. Simply enter the angle value into the calculator choose between degrees and radians, and it will automatically calculate the cosine of the angle for you. This tool is perfect for students, engineers, and anyone else who needs to calculate the cosine of an angle quickly and accurately.

What is Cosine of an Angle?

Cosine of an angle is a trigonometric function that calculates the ratio of the adjacent side of a right triangle to its hypotenuse. It is abbreviated as cos and is used extensively in mathematics, physics, and engineering to solve problems involving angles.

Cosine of Angle Formula

The formula for finding the cosine of an angle is:

cos( α ) = \dfrac{\text{adjacent side}}{\text{hypotenuse}}

Where α is the angle, adjacent side is the side adjacent to the angle, and hypotenuse is the longest side of the right triangle.

Example 1:

Let's say you have a right triangle with an angle of 45 degrees. To find the cosine of the angle, you can use our cosine of angle calculator. Simply enter 45 as the angle value choose degrees from the select box, and the calculator will tell you that the cosine of the angle is 0.7.

Example 2:

Suppose you have a right triangle with an angle of 54 degrees. Using our cosine of angle calculator, you can find the cosine of the angle by entering 54 as the angle. The calculator will tell you that the cosine of the angle is 0.58.
