What is Vector?

• Vector?

Vectors are mathematical objects that have both magnitude(size) and direction.

Traditionally, vectors are represented as arrows starting from a specific point called the origin. However, vectors do not necessarily have to start at the origin. They can be located anywhere in space. The origin is often used as a convenient reference point, but the vector is determined by its length and direction, not its starting location.

• Calculating the Magnitude of a Vector

• Trigonometry and Vectors

Trigonometry is closely related to vectors, as it can be used to analyze the direction and magnitude of vectors. Some key concepts include:

• The law of sines and cosines, which relate the sides and angles if a triangle.
• Polar coordinates, which can be used to represent vectors in terms of magnitude and angle.

These trigonometric concepts have many applications in physics, engineering, and other fields that involve the use of vectors.
