Perform vector operations in \ (\mathbb {R}^ {3}\). Vectors are useful tools for solving two-dimensional problems. Life, however, happens in three dimensions.
Vectors in 2D and 3D [all mathematics is done by specifying position of the spacecraft and the moon relative to some coordinate system, say centered at the earth; that's how orbits are calculated at JPL and NASA]
Vectors in three dimensions. The concept of a vector in three dimensions is not materially different from that of a vector in two dimensions. It is still a quantity with mag- nitude and direction, except now there is one more dimension.
A vector is a quantity that has both a magnitude (or size) and a direction. Both of these properties must be given in order to specify a vector completely. In this unit we describe how to write down vectors, how to add and subtract them, and how to use them in geometry.
understand vectors, and math in general, you have to be able to visualize the concepts, so rather than developing the geometric interpretation as an after-thought, we start with it. 1.1 Vector addition and multiplication by a scalar We begin with vectors in 2D and 3D Euclidean spaces, E2 and E3 say. E3 corresponds to our
