## Use of Rotation Calculator:

A Rotation Calculator is used to compute the new coordinates of a point after it has been rotated by a specified angle around the origin. This is essential in various applications like graphics programming, navigation systems, and geometric transformations.

## Formula of Rotation Calculator:

X = x * cos(θ) - y * sin(θ) Y = x * sin(θ) + y * cos(θ)

**How to Use Rotation Calculator:**
1. Enter the x and y coordinates of the point to be rotated.

2. Specify the angle of rotation and choose the unit (Degrees or Radians).

3. Select the direction of rotation (Clockwise or Counter Clockwise).

4. Click "Calculate" to see the rotated coordinates. Use the "Clear" button to reset the form.

## Frequently Asked Questions:

### 1. What is the difference between degrees and radians?

Degrees and radians are two units for measuring angles. Degrees are based on dividing a circle into 360 parts, while radians are based on the radius of a circle. 180 degrees is equivalent to π radians.

### 2. How do I convert degrees to radians?

To convert degrees to radians, use the formula: radians = degrees × (π / 180).

### 3. Why would I choose clockwise or counterclockwise rotation?

The choice of rotation direction depends on the desired outcome. Clockwise rotation is typically used in standard coordinate systems, while counterclockwise may be used for certain transformations or visual effects.

### 4. Can this calculator handle negative angles?

Yes, the calculator can handle negative angles. A negative angle represents rotation in the opposite direction (e.g., a -45° rotation is clockwise).

### 5. What if I enter incorrect values?

Ensure that all input values are numeric and correctly entered. The calculator will not process if inputs are missing or invalid. Clear the fields and re-enter the values.

### 6. How accurate is the rotation calculation?

The rotation calculations are precise up to two decimal places. For more precision, you may need to use advanced mathematical tools or software.

### 7. Can I use this calculator for 3D rotations?

This calculator is designed for 2D rotations. For 3D rotations, additional parameters and calculations involving axes of rotation are required.

### 8. How does the calculator handle large angles?

The calculator can handle large angles by converting them into their equivalent within a 360-degree range or 2π radians, ensuring accurate results.

### 9. What should I do if the result seems incorrect?

Double-check your inputs and ensure that the angle unit and direction are correctly selected. Verify the calculations manually if necessary.

### 10. Is there a way to visualize the rotation?

Currently, this tool does not offer visualizations. For graphical representation, you might use software that supports geometric transformations or graphing capabilities.
