Last time I have written about the dot product of unit vectors that is:
Today I will discuss about the cross product of unit vectors:
i x j = k
j x k=i
k x i =j
j x i= -k
k x j= -i
i x k= -j
i x i = j xj = k x k =0
Do you know how the above results come? If your answer is no, then let us discuss it: Continue reading “cross or vector product of unit vectors”
Coordinate system is used to represent any point, say P(x, y, z ) in space. There are many methods by which this can be done, but there are three simple methods, which we will discuss in this article.
Types of coordinate systems are :
I. Cartesian or rectangular coordinate system.
II Cylindrical coordinate system
III Spherical coordinate system.
Today I will discuss briefly about the cartesian or rectangular coordinate system:
