### How Excel Formula Calculate Degrees of Angle

Microsoft Excel uses radians as a unit of measurement of angle or degree.

1 (one) radians is equal to 57.29577951 degrees or rounded to 57.296.

1 (one) radians is equal to 180 degrees divided by Pi (22/7).

Therefore the measurement in degrees must be converted into radians for accurate calculation results. Following are the sine, cosine, and tangent formulas:

sine of 90 degrees
=SIN(90/57.296)
the result is 1

cosine 90 degrees
=COS(90/57.296)
the result is 6E-06 or rounded to 0

tangent 45 degrees
=TAN(45/57.296)
the result is 0.999993955 or rounded to 1.

The formula on the above examples are already syntactically correct or correct writing format, so that it can be copied and pasted on an Excel sheet, as shown below.

Changes from degrees to radians can be done by the RADIANS formula.
example of changing 90 degrees to radians:

the result is 1.570796327

And to convert radians to degrees can use the DEGREES formula.

=DEGREES(1.570796327)
the result is 90

For the inverse formula of the above function or arc are as follows:

arcsinus 0.5
=ASIN(0.5)

to get directly into unit of degrees the formula is
=DEGREES(ASIN(0.5))
the result is 30 degrees

arccosinus 0.5
=ACOS(0.5)

to go directly to units of degrees the formula is
=DEGREES(ACOS(0.5))
the result is 60 degrees

arctangen 0.5
=ATAN(0.5)

to get directly to units of degree the formula is
=DEGREES(ATAN(0.5))
the result is 26.56505118 degrees

The ATAN formula can be used to calculate the angle of the house roof.
