## What Is SIN Excel Function?

The

SIN Excel Functioncalculates theSINEvalue of the given angle. To calculate theSIN function, the input values must be compatible with the formula, else we can use theRadiansfunction or convert to the angle to degrees using the expression [PI()/180].

The **SIN function** is an inbuilt “**Math and Trig**” function, so we can insert the formula from the “**Function Library**” or enter it directly in the worksheet.

For example, the image below depicts the Value in column A. We will apply the **SIN function **to calculate the **SIN** values.

Select cell **B2**, enter the **SIN Excel ****formula **** =SIN(A2 * PI() / 180), **and press “

**Enter**”.

The result is ‘**0.866’**, as shown above. Column C is for our reference.

###### Key Takeaways

- The
**SIN Excel****function**is a trigonometric function that returns the**SINE**of an angle. - The
**SIN function**accepts the**SIN**angle values in degrees. If the values are not in the required way, we can convert the values to degrees, i.e., for ex. 80 to 80^{o}, using the expression [PI()/180], or use the**RADIANS function**. - To calculate the
**SINE value,**we use the**SIN()**function along with other functions such as**PI(), RADIANS(), DEGREES(),**etc. - The
**PI()**function helps us derive the accurate results while working with**π.**

### How To Use SIN Excel Function?

We can use the **SIN function **using 2 ways, namely:

**Access from the Excel ribbon.****Enter in the worksheet manually.**

#### Method #1 – Access from the Excel ribbon

Choose an empty cell for the result → select the “**Formulas**” tab → go to the “**Function Library**” group → click the **“Math & Trig” **option drop-down → select the “**SIN**” function, as shown below.

The **“Function Arguments” **window appears. Enter the arguments in the **“Number”** field, and click “**OK**”, as shown below.

#### Method #2 – Enter in the worksheet manually

- Select an empty cell for the output.
- Type =
**SIN**( in the selected cell. [Alternatively, type**=S**or**=SI**and double-click the**SIN function** - Enter the argument as cell value or cell reference in excel and close the brackets.
- Press the “
**Enter**” key.

The succeeding example depicts the values, and we will calculate the **SIN** value using the **SIN Excel function **combined with the **RADIANS function**.

In the table, the data is,

- Column A contains the Value.
- Column B contains the Result.

The steps to calculate the value using the **SIN excel formula **are,

**Select cell B2, and enter the formula =SIN(RADIANS, i.e., the value of the Radian function.****Enter the value of the ‘angle’ as A2, and close the brackets. The complete formula is =SIN(RADIANS(A2))****Press the “Enter” key. The result is “0.0175”, as shown below.****Drag the formula from cell B2 to B6 using the fill handle. The output is shown below.**

### Examples

We will consider some advanced scenarios using the **SIN Excel function examples.**

#### Example #1

The succeeding example depicts the values, and we will calculate the **SIN** value using the **SIN **and the** RADIANS functions**.

In the table, the data is,

- Column A contains the Value.
- Column B contains the Result.

The steps to calculate the value using the **SIN formula **are,

**Step 1:**Select cell**B2**, enter the formula, and press the “*=SIN(RADIANS(A2))***Enter**” key. The result is “-**0.819**”, as shown below.

**Step 2:**Drag the formula from cell**B2**to**B6**using the fill handle. The output is shown below.

#### Example #2

The succeeding example depicts the values, and we will calculate the **SIN** value using the **SIN **and the** DEGREES function**.

In the table, the data is,

- Column A contains the Value.
- Column B contains the Result.

The steps to calculate the value using the **SIN formula **are,

**Step 1:**Select cell**B2**, enter the formula, and press the “*=SIN(DEGREES(A2))***Enter**” key. The result is “**0.9276**”, as shown below.

**Step 2:**Drag the formula from cell**B2**to**B6**using the fill handle in excel. The output is shown below.

#### Example #3

The succeeding example depicts the values, and we will calculate the **SIN** value using the **SIN, PI excel function, **and** RADIANS functions**.

In the table, the data is,

- Column A contains the Value.
- Column B contains the Result.
- Column C contains the Formula.

The procedure to calculate the value using the **SIN formula** is,

Enter the formulas as follows:

in cell*=SIN(PI())***B2**,in cell*=SIN(PI() /2)***B3**,in cell*=SIN(A2 * PI() / 180)***B4**, andin cell*=SIN(RADIANS(A2))***B5**.- After entering each formula, press the “
**Enter**” key.

The results are shown above from cells **B2 **to** B5**. Column C is for our reference.

#### Example #4

The succeeding example depicts the values, and we will calculate the **SIN** value using the **SIN **and the** DEGREES function**.

In the table, the data is,

- Column A contains the Value.
- Column B contains the Result.

The steps to calculate the value using the **SIN formula **are,

**Step 1:**Select cell**B2**, enter the formula, and press the “*=SIN(DEGREES(A2))***Enter**” key. The result is “-**0.014**”, as shown below.

**Step 2:**Drag the formula from cell**B2**to**B6**using the fill handle. The output is shown below.

### Important Things To Note

- We get the
**“#VALUE!”**error when the selected cell value or cell reference is non-numeric. - If the cell value is blank, then, by default, the formula will return the output as
**0**. - We get the
**“#NAME?”**error when the function name is incorrect.
