## **SEC Function – Explanation:**

- This function **returns the** **Secant values (ratio) of the given (angle) radians**.
- To convert the degree value into radians, use **RADIANS(number)** function.
- For example, **RADIANS(0.785)** returns the **secant value as 1.41365**

## **Syntax:**

**=SEC(number)**

### Argument Explanation:

**Number ** – The angle in radians to which you need to find the **secant value**.

### Note:

- If the argument is a non-numeric value (letters and special characters) and then it returns **#VALUE!** Error.

## **Examples:**

Let’s see some example to know how it works.

### Example 1:

- In the following screenshot, you can see the degree values in **Column A** , its corresponding radians in **Column B**.
- To convert the degree values into radians, you need to use the following **RADIANS Function** and its syntax is:
- **=RADIANS(degree)**
- The output secant values are listed in **Column C**.

### Example 2:

- To **convert the degrees into a secant value** , use the below formulas.

**=SEC(degree)\*PI()/180** or **=SEC(RADIANS(degree))**
