1. What Are Vector Components?

Vector components break down a vector into its horizontal and vertical parts. This is essential in physics, engineering, and mathematics for analyzing forces, velocities, and other vector quantities in different directions.

2. How Does The Calculator Work?

The calculator uses the trigonometric component equations:

Where:

• \( Magnitude \) — The length or size of the vector
• \( Angle \) — The direction of the vector measured in degrees from the horizontal axis
• \( H \) — Horizontal component (x-axis projection)
• \( V \) — Vertical component (y-axis projection)

Explanation: The calculator converts the angle to radians, then applies trigonometric functions to decompose the vector into its orthogonal components.

3. Importance Of Component Calculation

Details: Component analysis is crucial for solving physics problems involving multiple forces, analyzing motion in two dimensions, and understanding vector operations in engineering applications.

4. Using The Calculator

Tips: Enter the magnitude as a positive value. The angle can be positive or negative, measured from the positive x-axis (0° = right, 90° = up, 180° = left, 270° = down).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between degrees and radians?
A: Degrees use a 360° circle while radians use 2π. This calculator accepts degrees and automatically converts to radians for computation.

Q2: Can I use negative angles?
A: Yes, negative angles represent clockwise rotation from the positive x-axis.

Q3: What if my vector is in different quadrants?
A: The trigonometric functions automatically handle all quadrants, giving appropriate positive/negative values for components.

Q4: How accurate are the results?
A: Results are calculated to high precision (4 decimal places) using PHP's built-in trigonometric functions.

Q5: Can I use this for 3D vectors?
A: This calculator is for 2D vectors only. For 3D vectors, you would need additional calculations for the z-component.
