What is the Exact Value of sin Degrees? Though the exact reason for choosing degree as a unit of angle and rotation is not known there are reasons to believe that it was a part of the sexagesimal numeric system. There are evidences to suggest that the earliest trigonometry which was used by Babylonian astronomers and also their Greek successors made use of Degree as a unit of measurement. There are also empirical evidences to suggest that Indian might also have used degrees and it is clearly mentioned in the Rigveda an ancient collection of Hindu Hymns.

It must have been written sometime during the — BCE. Radians are another commonly used and standard unit for measuring and are extensively used in mathematics. According to this measurement the arc length of a unit circle must be equivalent numerically to the radian measurement of the angle which it subtends. To put in other words one radian is roughly equivalent to around Formerly this unit was referred to as a supplementary unit, but eventually this was abolished sometime during Hence today when we talk about radian it is considered as SI derived unit measurement.

The entire concept of radian measure is perhaps the brainchild of Roger Cotes and he discovered it in He was able to describe and explain everything pertaining to radian but was not able to name it. Well, we specified that our radius was the value of 1, right?

So, if we then want to calculate our circumference of this unit circle, our distance around would be 2pi. Ah, now I see. Well, now that we know that degrees rotational measure equals 2pi radians distance measure , we can switch back and forth quickly and easily.

But why do we even have to do this? In more advanced mathematics, the use of radian measure is preferred and often required to solve problems. To deal limits and derivatives, which helps us to explain how things change over time, we have to use radians — and over time, you will see that radians are easy, fun, and very, very helpful!

Converting degrees to radians formula is a generalized formula used to convert the given value in degrees to value in radians. These statements can be equated as:. Degrees to Radians Equation: The relation between degree measure and radian measure can be represented with this equation:.

We can follow the steps given below to calculate the measure of an angle given in degrees to radians. The below-given table shows the radian values for the corresponding angle measures in degrees. The below-given chart shows degree measures and their corresponding radian measures. We can also use this chart to convert the degrees to radians to make the calculations easier and faster. Example 1: In a circle with center O, points A and B are two points on the circle. Example 2: Katie bought a pizza from a nearby store.

Katie asked her mother about the central angle that her slice of pizza made. Can you help Katie find the measurement of the angle in degree and radian? Solution: To convert the following degree measure to radians we will use the following steps:.
