Examples
Here are a few example use cases that explain how to use theSIN
formula in Google Sheets.
Calculate the sine of an angle
One of the main uses of the SIN
function is to calculate the sine of an angle in radians. This is useful in a variety of applications, such as physics, engineering, and mathematics.
Model periodic phenomena
Sine functions are used to model a wide range of periodic phenomena, including waves, oscillations, and vibrations. By using the SIN
function in a formula, you can create models that simulate these phenomena.
Create visualizations
In Google Sheets, you can use the SIN
function to create visualizations of sine waves and other periodic phenomena. By plotting the output of the function over time, you can create graphs that show how these phenomena change over time.
Common Mistakes
SIN
not working? Here are some common mistakes people make when using the SIN
Google Sheets Formula:
Invalid input
The angle provided to the SIN function must be in radians. If you provide an angle in degrees, you need to convert it to radians first using the RADIANS function.
Incorrect function name
Make sure you are using the correct function name. The correct function name for the sine function is SIN, all capital letters.
Mismatched parentheses
Check that you have correctly balanced parentheses in your formula.
Related Formulas
The following functions are similar to SIN
or are often used with it in a formula:

COS
The
COS
function in Google Sheets returns the cosine of an angle provided in radians. It is commonly used in trigonometry to calculate the cosine of an angle. The function takes one parameter, the angle in radians. 
TAN
The
TAN
function returns the tangent of an angle specified in radians. Tangent is the ratio of the length of the opposite side to the length of the adjacent side of a rightangled triangle. This function is commonly used in trigonometry and geometry calculations. 
ASIN
The ASIN function returns the arcsine of a value in radians, which is the angle whose sine is the specified value. This function is commonly used in trigonometry and geometry calculations. When used in a formula, the ASIN function takes a single argument, the value for which to calculate the arcsine.

ATAN
The
ATAN
function returns the arctangent of a value in radians, which is the angle whose tangent is a given value. This function is commonly used in trigonometry and geometry to calculate angles. The returned angle is in the range π/2 to π/2.
