This article describes the formula syntax and usage of the SIN function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Returns the sine of the given angle.
The SIN function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Number Required. The angle in radians for which you want the sine.
If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.
The workbook below shows examples of this function. Inspect them, change existing formulas, or enter your own formulas to learn how the function works.
