Can you use the result or the method for some other problem? Many of the entries overlapped. But he should not only understand it, he should also desire its solution. Look at the un- known! Example 7 data, the condition.

The com- ing of a bright idea is an experience familiar to every- body but difficult to describe and so it may be interesting to notice that a very suggestive description of it has been incidentally given by an authority as old as Aristotle. It is written in a somewhat awkward style, to an audience that is difficult to discern, and with enough repetition that I had to skip pages at a time to get to the next topic. Or observing that the bright side of the moon is always toward the sun, you may suddenly per- ceive why this is; namely, because the moon shines by the light of the sun. Not entirely satis- fied with our derivation of the result, we wish to improve it, to change it. One of the first and foremost duties of the teacher is not to give his students the impression that mathematical problems have little connection with each other, and no connection at all with anything else. The main work, the discovery of the plan, was described in section This book really changed how I see math, especially abstract math.

While the writing is a bit clunky Polya was a mathematician and English was not his first languagethe ideas are so deeply useful that they continue to have relevance not just for solving mathematical problems, George Polya ‘s classic How to Solve It is a seminal work in mathematics education. I have a ploya deeper understanding and appreciation for abstract math after reading this book.

We draw a figure in which we easily place a and h.

How to Solve It: A New Aspect of Mathematical Method

The teacher may show the der- ivation of new problems from one just solved and, doing so, provoke the curiosity of the students. They are parallel and equal to each other. Thus, if we wish to solve it with as little preliminary knowledge as possible, we should look around for a simpler analogous problem. However, some of the math examples were completely above my level of comprehension, and I had to bribe myself to read through those droll parts to understand what the author was trying to illustrate rather than just skipping.


Connecting these facts suitably, we may prove that the 6 median planes have a pgoblem point.

We have not had any problem yet about the diagonal of a parallelepiped. Yet most of the time especially in the third part the point of view is that of a person who is neither teacher nor student but anxious to solve the problem before him.

Then, the teacher should show them, at least once or twice, not only how to solve the problem more shortly but also how to find, in the result itself, indications of a shorter solution.

The worst may happen if the student embarks upon computations or construc- tions without having understood the problem. The relation connecting the unknown and the data is the same in both problems, the old and the new.

How to Solve It: A New Aspect of Mathematical Method by George PĆ³lya

This book shows you -“How to Solve it”. Have you taken into account all essential notions involved in the problem? Should we introduce some auxiliary element in order to make its use possible? There is an obvious analogy between her difficulties and our difficulties.

The following principle is plausible and presents itself naturally. What we have to prove is a fundamental theorem of solid geometry.

The organization of his techniques is alphabetical by title and Polya does not attempt to offer any over arching structure to his techniques. Each example that Polya gives takes concentration and critical analysis.

Merohedral isomorphism may be considered as another very precise sort of analogy. What can the teacher do in order to obtain this best possible result? Question and suggestion aim at the same effect; they tend to provoke the same mental opera- tion. The center of gravity of a triangle divides the distance between any vertex and the midpoint of the opposite side in the proportion 2: The following pages are written somewhat concisely, but as simply as possible, and are based on a long and serious study of methods of solution.


Convince yourself of the correctness of each step by for- mal reasoning, or by intuitive insight, or both ways if you can. This task is not oslving easy; it demands time, practice, devotion, and sound principles.

Trivia About How to Solve It: Thanks to such guidance, the student will eventually discover the right use of these questions and suggestions, and dolving so he will acquire something that is more important than the knowledge of any particular mathematical fact.

As for example, if you see a person talking with a rich man in a certain way, you may instantly guess that that person bulu trying to borrow money. If the reader is sufficiently acquainted with the list and can see, behind the suggestion, the action suggested, he m ay real- ize that the list enumerates, indirectly, mental operations typically useful for the solution of problems. If, using them properly, you address the same questions and suggestions to one of your students, you may help him to solve his problem.

Each side of one is parallel to the corresponding side of the other, and has also the same direction. They contain different notions; one is concerned with equality of the sides, the other with equality of the angles of a triangle.

Such tests take the form of careful experiments and measurements, and are combined with mathematical reasoning in the physical sciences.
