45 degrees in radians

The conversion from degrees to radians is a common mathematical operation that is used in many fields, including physics, engineering, and computer science. The degree is a unit of angle measure that is used in many different contexts, while the radian is a unit of angle measure that is based on the concept of a circle.

One degree is equal to 1/360 of a full revolution, or circle, around a point. In contrast, a radian is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. This means that the length of the arc (the radius) and the circumference of the circle are equal when measured in the same units of length.

To convert from degrees to radians, you can use the following formula:

radians = (degrees * pi) / 180

where pi (π) is a mathematical constant that is approximately equal to 3.14159.

In this case, 45 degrees is approximately equal to 0.7853981633974483 radians.
