*To determine the length and direction of a vector, you use mathematical calculations. The length, or magnitude, of a vector is found using the Pythagorean theorem, while the direction is determined using trigonometric functions like arctangent. These measurements are crucial for understanding and analyzing vectors in mathematics and physics, where both magnitude and direction play significant roles in describing physical quantities.*
