thumb_How to solve SSC CGL level problem in a few steps trigonometry 6

Some problems look difficult, but if you have a clear strategy of dealing with this type of problems, and is ready to change track by reevaluating the strategy midway, chances are high that you will reach the efficient solution in a few quick steps...

Trigonometry concepts part 3, maxima (or minima) of Trigonometric expressions

thumb_basic and rich trigonometry concepts part 3 maxima trigonometric expressions

Trigonometric functions behave not exactly like common algebraic variables, and so maximizing or minimizing an expression of trigonometric terms requires first conversion of the expression to a single function expression. Frequently the rich algebraic concept of AM GM inequality also comes handy for solving such problems...

thumb_How to solve a school math problem in a few direct steps rigonometry5

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....

SSC CGL level Solution Set 51, Algebra 12

thumb_SSC CGL solution set 51 algebra12

This is the 51st solution set of 10 practice problem exercise for SSC CGL exam and 12th 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...
