Step 1 of 3
Lecture 3 VECTORS In 1 dimension, we use + or – to indicate direction of a vector In 2 or 3D we need more than just a sign to indicate direction, such as an angle We express vectors as arrows, there the tail of the arrow is where the vector starts and the tip is where it ends. The length of the arrow represents the magnitude of the vector and the direction of the arrow represents the orientation of the vector Ay A Ax = Acosϴ Ay = Asin ϴ A = √Ax^2 = Ay^2 Ax Unit vector of a = (Axi + Ayj + Azk) position r = xi + yj + zk length r = √x^2 + y^2 + z^2 unit vector = x/r + y/r +z/r **If we have a magnitude for th
