Often a vector is specified by a magnitude and a direction; for example, a rope with tension t⃗ exerts a force of magnitude t=20n in a direction θ=35∘ north of east. this is a good way to think of vectors; however, to calculate results with vectors, it is best to select a coordinate system and manipulate the components of the vectors in that coordinate system. find the components of the vector a⃗ with length a = 1.00 and angle α=20.0 ∘ with respect to the x axis as shown in (figure 1) .
