This is the subject of this section.Suppose that we have to evaluate the sum given byFrom now on, to avoid clutter, we’ll write as simply , where the upper index should be understood to be present. Thus,This series can be generated using a manipulation involving differentiation, as follows:Consider thekkaktrihttp://www.blogger.com/profile/13079692037684889584noreply@blogger.com0tag:blogger.com,1999:blog-722757808418967792.post-43121768470428896312014-08-09T03:18:00.000-07:002020-10-13T16:31:54.784-07:00CHAPTER 1 - 3-D GeometryINTRODUCTION : BASIC FORMULA we need three non-co planar directions as our reference axis to specify the position of any point. It is most convenient to take the three non-coplanar directions (denoted conventionally by , and directions) as being mutually perpendicular to each other.Such a reference axes is termed a rectangular coordinate axis. Any point in space can now be specified with kkaktrihttp://www.blogger.com/profile/13079692037684889584noreply@blogger.com0tag:blogger.com,1999:blog-722757808418967792.post-36013056973301710562014-08-08T09:56:00.000-07:002020-10-13T16:19:07.417-07:00CHAPTER 1- VectorsIn very basic terms, a vector can be thought of as an arrow in the Euclidean plane. This arrow has a starting (initial ) point and an ending (final) point :This vector will be represented as . We thus see that a vector has two quantities associated with it:(a) a magnitude(b) a directionThese two quantities are necessary to carry someone from to ; these two quantities are sufficient to uniquely kkaktrihttp://www.blogger.com/profile/13079692037684889584noreply@blogger.com0
