3D geometry is one easy scoring area in engg entrance exam , but to improper teaching the students lose interest in this topic. In this class I will explain the equations in geometric sense.This will ensure students have visual memory of the equations improving their overall chance of cracking the questions in this easy scoring area.The geometrical meaning of equation of plane , line and the type of problems that can be created in this topic will be explained in detail. Apart from the past year problems alongwith complete analysis will be explained during the class.The students will be provided with some techniques to quickly solve questions without using pen and paper. Just by mere looking at questions the students will be answer the questions and choose the right answer! Besides the algebraic equations in three variables will also be discussed and their connection to plane and lines will also be taken up during the class. This is one Grey area which will be discussed during the class.
