The SIN function in Excel calculates and returns the sine of a given radians.
SIN(θ) = opposite / Hypotenuse = a/c
sin of the angle θ, is the ratio of the opposite side – a, to the hypotenuse – c.
Syntax of SIN Function in Excel
SIN(number)
Where Argument number is angle in radians which you need to calculate the Sine of.
NOTE: If your angle is in degrees, you will need to convert it into radians before supplying it to the SIN Function with the help of Radians function
=RADIANS( degrees )
Example of SIN Function in Excel
Formula
- In Row number 2 and 3 the radians value is passed to the SIN Function
- In row number 4, Angle 60 degree is converted to radians and passed as input to the SIN Function.
- In Row number 5 Radians -π/6 is passed as input to the SIN Function.
- In row number 6, Angle -90 degree is converted to radians and passed as input to the SIN Function.
