mathematics for 12th class part 1

How an ordinary student can score more than 60 marks in Mathematics for HSC Board exam?
Hello friends I am Anil Kore I will explain you how to score more than 60 marks with little study and with simple and selected topics in Mathematics for HSC Board Exam.
These videos are only for the students who are weak in mathematics or find difficulties in studying mathematics or they came from rural areas and also students from poor families.
These videos may help you to build a confidence to face HSC board exam. And score more than 60 marks.
There are certain chapters which do not required strong background of algebra and trigonometry an. By preparing these chapters an ordinary student can score more than 60 marks in board exam.
So we begin from 1st Section in this video and 2nd Section in my next video.
SECTION 1
The 1st chapter is Mathematical logic. It is most simple and student friendly. Free from need of algebra or trigonometry. You have to memorize 1. Truth Table of implication 2. Converse, Inverse and Contrapositive of an implication.

1. Matrices
   same as logic simple, student friendly. Free from algebra or trigonometry.
2. Pair of Lines
   You need basic knowledge of coordinate geometry and straight lines from 11th std.
   You have to memorize
3. the determinant of condition that a general equation of second degree in x and y represent pair of lines.
4. tangent of acute angle between pair of lines.
5. Vectors and 5. 3D geometry
   You need basic knowledge of coordinate geometry and straight lines from 11th std.
6. Linear programming
   You need basic knowledge of coordinate geometry and straight lines from 11th std.
   You only need to draw a rough sketch of graph in board exam.
   These are simple topics for maximum scoring in section 1.
