Cotangent Calculator – Calculate cot(x) for Degrees and Radians

## Similar Calculators:

Cotangent often denoted as \( \cot(x) \), is the reciprocal of the tangent function. In mathematical terms, it can be expressed as:

This function represents the ratio of the adjacent side to the opposite side in a right triangle. Cotangent is widely used in trigonometry and can help solve various real-world problems involving angles and distances.

## Calculating Cotangent in Degrees

### Using the Basic Formula

To calculate cotangent in degrees, you’ll typically use the following formula:

#### Example: Cotangent of 45 Degrees

Let’s take an example to illustrate this. Suppose we want to find the cotangent of 45 degrees. Using the formula:

Now, we know that \( \tan(45^\circ) = 1 \), so:

Hence, the cotangent of 45 degrees is 1.

#### Example: Cotangent of 30 Degrees

Similarly, if we want to find the cotangent of 30 degrees:

We know that \( \tan(30^\circ) = \frac{1}{\sqrt{3}} \), so:

Thus, the cotangent of 30 degrees is \( \sqrt{3} \).

## Calculating Cotangent in Radians

### Converting Degrees to Radians

Before we calculate cotangent in radians, it’s important to understand the conversion from degrees to radians. Recall that \( \pi \) radians are equivalent to 180 degrees. Therefore, to convert degrees to radians, you can use the formula:

#### Example: Cotangent of \( \frac{\pi}{4} \) Radians

Suppose we want to find the cotangent of \( \frac{\pi}{4} \) radians. First, we need to convert this angle from radians to degrees:

Now that we have the angle in degrees, we can apply the previous formula for cotangent in degrees:

Hence, the cotangent of \( \frac{\pi}{4} \) radians is 1.

#### Example: Cotangent of \( \frac{\pi}{6} \) Radians

Let’s find the cotangent of \( \frac{\pi}{6} \) radians. First, convert it to degrees:

Now, calculate the cotangent in degrees:

So, the cotangent of \( \frac{\pi}{6} \) radians is \( \sqrt{3} \).
