Hey guys sorry if this isn't in the right place, I'm new to these forums. Just wondering if someone could clarify to me what N25°W means? Is it 25 degrees west of north? Thank you!

A vector is a mathematical object that has both magnitude (size) and direction. It is represented by an arrow, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction.
To add or subtract vectors, you must first place them tail-to-tail, meaning the tail of one vector is lined up with the head of the other. The resulting vector is the sum or difference, respectively, of the two vectors. This process is also known as the "parallelogram law."
A scalar is a quantity that has only magnitude, while a vector has both magnitude and direction. Examples of scalars include time, temperature, and mass, while examples of vectors include displacement, velocity, and force.
The magnitude of a vector can be found using the Pythagorean theorem, where the length of the vector is the hypotenuse and the x and y components are the legs. The direction of a vector can be found using trigonometric functions, such as tangent or sine, to determine the angle of the vector relative to a reference direction.
Yes, vectors can have negative components. This represents the direction of the vector being in the opposite direction of the reference direction. However, the magnitude of a vector is always positive.
