I delivered the lecture on Mathematical Fun. It was delivered in Indian Language “Marathi”. If you understand Marathi, Please click here to see my Lecture on YouTube.

Secondly to think more about the studies of Mathematics, you are requested to participate in

__Program of Studies for Students and Parents__given in my previous Blog. (Blog-14)See the simple method of calculations for solving the Trigonometry Problem. There are so many methods to solve such type of problems. You also may have better solution for such type of problems, that can also shared with other students. Please see the following problem & it's solution which I find as easier one. If you have any other simple method, then please publish your method through this blog simply by writing the comments.

Solution:

Given: PR = 6 units, PQ 8 units

To Find: Area of the shaded Portion

1) In ∆ RPQ, Ð RPQ = 90° [Angle inscribed in Semicircle is right angle]

2) In ∆ RPQ, RQ

^{2}= PR^{2}+ PQ^{2}^{ }RQ

^{2}= 6

^{2}+ 8

^{2 }

^{ }RQ

^{2}= 36 + 64

^{ }RQ

^{2}= 100

^{ }RQ

^{ }= 10 Units.

3) Let radius of semicircle RxPm be r

_{1}, PsQn be r_{2}& RyPtQ be r_{3}The above problem is solved by calculating for each values of radii, 3, 4 & 5 separately by multiplying each term by 3.14 & 1/2 in so many books. Here one should know that

^{(}3

^{2}+ 4

^{2}– 5

^{2}) = 0. So here you need not multiply all the three radii by 3.14 & 1/2. That's why I would like to tell you to think very properly & improve your application of thinking any where.

Thinking in this direction will definitely improve your skills & the same can be utilized by you to apply every where.

I simply don't want to tell you to go with this simple method of calculation. I want that slowly, you need to mold yourself and improve the thinking level. Only using this technique for solving some problem and getting good scores will not serve my purpose. I want that the entire world need to improve the thinking skills so that every one can invent so many beautiful things of the human life.

This is possible only with the help of students like you along with your parents.

Please come ahead and start this beautiful work for yourself and show to the world that we can also build the world with powerful thinking level as every one is competent.
