While working with trigonometric functions, sometimes we are required to use a square of either the sine, cosine or tangent. This can be challenging, especially if you are not aware of how it is written. This article provides a clear guide on how to write and use SIN squared in excel.

**Example**

For illustrative purposes, let us consider the following example;

*Figure 1: Sine squared in excel*

In this example, we have the angle, marked as X. we also have the sine of the angle, marled as SIN(X). The sine squared is marked as SIN(X)^2 in column C.

To get the sine squared we simply square the sine. This can be done as shown below;

**=SIN(X)^2**

Note that the results for the sine squared do not have negative. This is because the negatives shall cancel each other during the multiplication to only remain with positives.
