How to solve difficult SSC CGL level School Math problems in a few quick steps, Trigonometry 5

thumb_How to solve SSC CGL level school math problems in a few quick steps trigonometry5

In procedural approach to solve Trigonometry or Algebra problems, usually the student has to go through many steps writing the steps using pen and paper without using the useful patterns lying partly hidden in the problem waiting to be used with intelligence so that the solution is reached in a few steps lightning fast, that too without using pen and paper. We are not discussing tricks. We are discussing the anatomy of a rich concept that are based on basic concepts and how a specific rich concept can be used for what we call, efficient problem solving.

How to solve SSC CGL level number and age ratio problems lightning fast

thumb_How to solve SSC CGL level number and age ratio problems lightning fast

Use of a rich ratio concept based on a most basic ratio concept helps to solve a broad spectrum of ratio problems and specifically many standard number or age ratio problems elegantly in a few steps much faster than conventional procedural methods...

Basic and Rich Geometry Concepts Part 7, Laws of sines and cosines

thumb_basic and rich geometry concepts part 7 laws of sines and cosines proofs top

What if we need to relate the sides of a triangle with the angles? Except Pythagoras theorem there is little help in the area of establishing a relationship between the sides and the angles of a triangle. The laws of sines and the laws of cosines meet this important gap...

Basic and Rich Geometry Concepts Part 5, Proof of Median relations

thumb_basic and rich geometry concepts part-5 medians concept proofs top

Medians form one of the most important set of components in a triangle closely tied to the triangle independent of any other geometric shape. In this discussion we will explain what are medians and their relations with the sides of the triangle along with the proofs...

Basic and Rich Geometry Concepts part 4, Proof of arc angle subtending concept

thumb_Basic and rich geometry concepts part 4 proof arc angle subtending

To explain the Arc angle subtending concept exhaustively and comprehensively, we will use four different configurations and the corresponding mechanisms along with solving a specially selected problem. To be exhaustive, we needed to follow a systematic method...

SSC CGL level Solution Set 37, Geometry 5

thumb_SSC CGL level solution set 37 geometry-5

This is the 37th solution set of 10 practice problem exercise for SSC CGL exam and 5th on topic Geometry. You need to take the corresponding test first before referring to this solution set. As expected some of the problem pictorial representation seemed to be complex, but once you represent a geometric figure properly even in a quick sketch, rest should not take much time...

SSC CGL level Solution Set 35, Algebra

thumb_SSC CGL solution set 35 algebra10

This is the 35th solution set of 10 practice problem exercise for SSC CGL exam and 10th on topic Algebra. For maximum gains, the test should be taken first, that is obvious. But more importantly, to absorb the concepts, techniques and deductive reasoning elaborated through these solutions, one must solve many problems in a systematic manner using this conceptual analytical approach. One can learn well only by practicing learning by doing...
