After crossing the first barrier in the process of proving a Trigonometric identity, if you go straight ahead without looking at the goal state on the RHS, you might reach a situation where you would have to start again from the goal state expression and backtrack to the simple result you had reached on the first go, not only an awkward solution but also technically an invalid one....

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.

SSC CGL Tier II level Solution Set 7, Trigonometry 1

thumb_SSC CGL Tier 2 solution set 7 trigonometry1

This is the 7th solution set of 10 practice problem exercise for SSC CGL Tier II exam and 1st on topic Trigonometry. Students should complete the corresponding question exercise in prescribed time first and then only refer to this solution set. Some of these 10 questions may seem to be difficult at first glance...

SSC CGL Tier II level Solution Set 4, Geometry 1

thumb_SSC CGL Tier2 level solution set 4 geometry1 top

This is the 4th solution set of 10 practice problem exercise for SSC CGL Tier II exam and the 1st on topic Geometry. 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...

Basic and rich Trigonometry concepts part 2, proof of compound angle functions

thumb_basic and rich trigonometry concepts part 2 compound angle relations proofs top

Trigonometry first established relationships between the angle and side measurements of a right angled triangle by defining trigonometric functions and thus extended the reach of mathematics wonderfully. Like any other branch of mathematics, from the basic trigonometric function definitions more advanced function relations are built stage by stage. Here we will deal with compound angle trigonometric function relations in more details...

Basic and rich Trigonometry concepts and its applications

thumb_trigonometry basic and rich concepts

Trigonometry first established relationships between the angle and side measurements of a right angled triangle by defining trigonometric functions and thus extended the reach of mathematics wonderfully. At first look we may not find much application of trigonometry in real world, but one must consider, the modern civilization is based on the sinusoidal frequencies that are nothing but trigonometric functions...
