For the simple right-angled triangle below, the sine of the angle θ, is the ratio of the opposite side, o, to the hypotenuse, h.
I.e. for the triangle above,
The Excel SIN function calculates the sine of a given angle.
The format of the function is :
Converting from Degrees to Radians
If your angle is in degrees, you will need to convert it into radians before supplying it to the Sin function.An example of this is given below.
Column A of the spreadsheet below, shows examples of the Excel Sin Function, used to calculate the sine of different angles.
Note that in the above examples:
Further information and examples of the Excel Sin function can be found on the Microsoft Office website.
