SIN Excel function is an inbuilt trigonometric function in excel which is used to calculate the sine value of given number or in terms of trigonometry the sine value of a given angle, here the angle is a number in excel and this function takes only a single argument which is the input number provided.
Syntax: =SIN (number)
The SIN function syntax has the following arguments:
- number – The angle in radians for which you want the sine.
Example: Let’s look at some Excel SIN function examples and explore how to use the SIN function as a worksheet function in Microsoft Excel:
Based on the Excel spreadsheet above, the following SIN examples would return:
- The SIN function returns the sine of an angle provided in radians. In geometric terms, the sine of an angle returns the ratio of a right triangle’s opposite side over its hypotenuse. For example, the sine of PI()/6 radians (30°) returns the ratio 0.5. ( =SIN (PI()/6) returns 0.5).
- Convert the number as required in Radian or Degree using either RADIANS function or DEGREES function .
- You can use PI() function to get exact results of SIN function while working with π.
