We can find the TANGENT of an angle by using the **TAN** function and the **RADIANS** function. This can also be done by using the **TAN **and **PI** function.

*Figure 1: Result of the TAN function for 30, 45, and 60 degrees*

**Using the TAN and RADIANS function**

The **TAN** function returns the tangent of an angle that is in **RADIANS.** Hence, for us to use the **TAN** function here, we must first convert the angle to **RADIANS**.

**Syntax**

`=TAN(RADIANS(ANGLE))`

**Setting up the Data**

We will find the tangent of the following angles by using the TAN function; 30, 45 and 60 degrees.

- We will place the angles in
**Column A** - Our formula will be placed in
**Column B**to display the result

* Figure 2: How to use the TAN function*

**The Result**

- We will input the formula below into
**Cell B4**:

**=TAN(RADIANS(A4))**

* Figure 3: How to use the TAN function*

- We will now press
**ENTER**to obtain the result

* Figure 4: Result of the TAN function using Radians*

- We will use the drop-down feature to get the results for 45 and 60 degrees

* Figure 5: Result of the TAN function for 30, 45, and 60 degrees*

**Using the PI function**

We can also use the PI function to tackle this. The formula with the PI function is given below:

**=TAN(A4*PI()/180)**

* *Figure 6: Using the PI function for 30 degrees

As done before, we will use the drop-down arrow to get the result for 45 and 60 degrees.
