We may classify the NCERT class 10 Trigonometry problems we will solve in this session as elegant within a minute problems, where conventional deductions may take a backseat leaving the lead to pattern and method based high speed problem solving...
The chosen problem this time is not so difficult, and on most occasions it will be solved conventionally. But driven by the general objective of equalizing the denominators, if the lightly hidden key pattern is discovered, everything becomes easy and straightforward with solution only a few light steps away...
Concept based approach provided the initial breakthrough and elegant solution in a few more steps achieved using trigonometry problem solving techniques.
Learn to solve SSC CGL cosine trigo problems faster with a unique technique. Save time on your exam by applying this efficient problem-solving approach.
Usually we solve difficult Algebra problems in a few steps using basic and rich Algebra concepts together with powerful general problem solving techniques visualizing the solution in the beginning itself. But this problem required more of deductive reasoning, mathematical reasoning, and exploratory application of core algebraic concepts such as symmetry in algebraic expressions, variable number reduction by component expression substitution and secondary term value sharing...
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...
Basic profit and loss concepts though are simple, which of the price values to be used as reference for applying profit or discount percentages sometimes create doubts. Further, the free offer concept and easily visible option for calculation of actual price values not only complicates the situation, but introduces harmful calculation delay...
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....
In this session of efficient math problem solving we will show how a difficult SSC CGL level percentage problem can be solved in seconds by using very basic number domain concepts along with basic percentage concepts...
Usually we solve difficult Algebra problems in a few steps using basic and rich Algebra concepts and techniques together with powerful general problem solving techniques. This problem required more of deductive reasoning, enumeration, mathematical reasoning, general problem solving techniques and core algebraic concepts such as symmetry in algebraic expressions and less of algebraic expression manipulation...
