# Learn ACOT() Function – How to use with Examples

The ACOT function in Microsoft Excel is an inverse cotangent function that returns the inverse cotangent of a number, expressed in radians. In other words, it calculates the angle whose cotangent is a given number.

To use the ACOT function, you need to enter the formula =ACOT(number) in the cell where you want the result to appear, replacing “number” with the value for which you want to find the inverse cotangent.

### Here are ten examples of using the ACOT function in Microsoft Excel:

The `ACOT` function in Microsoft Excel calculates the inverse cotangent of a number, in radians.

To use the `ACOT` function, simply enter `=ACOT(number)` in a cell, where `number` is the argument you want to find the inverse cotangent of.

Here are some examples of how you can use the `ACOT` function in Microsoft Excel:

1. `=ACOT(1)` returns `45°` or `0.785398163 radians`.
2. `=ACOT(-1)` returns `-45°` or `-0.785398163 radians`.
3. `=ACOT(0)` returns `90°` or `1.570796327 radians`.
4. `=ACOT(2)` returns `30°` or `0.523598775 radians`.
5. `=ACOT(-2)` returns `-30°` or `-0.523598775 radians`.
6. `=ACOT(0.5)` returns `63.43494882°` or `1.107148718 radians`.
7. `=ACOT(-0.5)` returns `-63.43494882°` or `-1.107148718 radians`.
8. `=ACOT(0.25)` returns `69.11208295°` or `1.249045772 radians`.
9. `=ACOT(-0.25)` returns `-69.11208295°` or `-1.249045772 radians`.
10. `=ACOT(10)` returns `6.19236561°` or `0.1047197551 radians`.

### Similar to ACOT Function in MS Excel

Similar functions include `ATAN` (inverse tangent), `ASIN` (inverse sine), and `ACOS` (inverse cosine). Each of these functions calculates the inverse trigonometric value of a number.

### FAQs on the ACOT function:

What is the difference between the ACOT function and the ATAN function?

The ACOT function returns the inverse cotangent of a number, while the ATAN function returns the inverse tangent of a number.

Can I use the ACOT function with negative numbers?

Yes, you can use the ACOT function with both positive and negative numbers.

How does the ACOT function calculate the inverse cotangent of a number?

The ACOT function uses a mathematical formula to calculate the inverse cotangent of a given number

Can I use the ACOT function in other Microsoft Office applications?

No, the ACOT function is only available in Microsoft Excel.

How can I convert the result of the ACOT function from radians to degrees?

You can use the RADIANS or DEGREES function to convert the result of the ACOT function from radians to degrees or vice versa.
