GET SINE Value using SIN Function in Excel

The SIN function in Excel calculates and returns the sine of a given radians.

Trigonometric Function in ExcelSIN(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

SIN Function in Excel 1

  • 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.
