I have several books of proofs such as:

$\color{blue}{\text{Book of Proof}}\text{ by }\color{green}{\text{Richard Hammack}}$

$\color{blue}{\text{Proofs: A Long-Form Mathematics Textbook}}\text{ by }\color{green}{\text{Jay Cummings}}$

and some other books in proofs. These are really excellent books, and there are many proof books that are good.

However I am looking for a book that contains many (basic) or (common) or (concrete, possibly hard)

$$\color{red}{\text{the following are just examples}}$$

  • There are infinitely many primes.

  • The irrationality of $\sqrt{2}, e, \pi, \dots$.

  • Derivation of quadratic formula, cubic formula, quartic formula.

  • There is no solution in radicals to general polynomial equations of degree five or higher with arbitrary coefficients (also known as Abel–Ruffini theorem).

  • The area of a circle $A=\pi r^2$, the volume of a sphere $V=\frac{4}{3}\pi r^3, \dots$.

  • The Pythagoras' theorem, $a^2+b^2=c^2$ where $a$ and $b$ are the legs, and $c$ is the hypotenuse of a triangle.

  • $\sin(\alpha \pm \beta)=\sin(\alpha)\cos(\beta) \pm \cos(\alpha)\sin(\beta)$, $\cos(\alpha \pm \beta) = \dots, \tan(\alpha \pm \beta) = \dots$.

  • Wilson theorem, any prime $p$ divides $(p-1)!+1$.

  • Fermat's little theorem.

  • Sine and cosine rules.

  • Intermediate value theorem, mean value theorem, Rolle's theorem, ...

  • The sum of the first $n$ natural numbers, the sum of the squares of the first $n$ natural numbers, the sum of the cubes of the first $n$ natural numbers.

  • The sum of $\text{A.P, G.P}$.

  • The derivation of Taylor series formula.

  • The integral of (even function or odd function) from $-a$ to $a$.

  • L'Hospital's rule.


The examples mentioned above are not all easy, for example Abel–Ruffini theorem, or the quartic formula, they are difficult. But I believe the are basic (basic in the sense of "knowing" the proofs/derivations).

So what I am looking for is a book that contain the proofs of formulae in different branches of mathematics, such as arithmetic, geometry, trigonometry, algebra, calculus, number theory, ...


I am afraid such book does not exist. But if exist, I highly recommend myself and everyone who is interested in maths to get this book.


Your help would be appreciated. THANKS!

  • any book of mathematics contains zillions of proofs – Masacroso Oct 29 '22 at 11:20
  • Honestly, this is your best option. – Bumblebee Oct 29 '22 at 11:34
  • @Masacroso I know that. So? – Hussain-Alqatari Oct 29 '22 at 11:47

    I think you are looking for "Proofs from THE BOOK" from Aigner. It covers a lot of different proofs from different topics. – garondal Oct 29 '22 at 11:50
  • Aside from perhaps a selection of notable proofs of some of these as in "Proofs from THE BOOK", there would be little reason for a book to contain both a proof of the infinitude of primes and something much more advanced like Abel-Ruffini. If you want a repository of proofs in one place without intending them to be read like in a textbook, then formalization of proofs of these are kept in lists like Formalizing 100 Theorems. – Mark S.

    To be clear, if there were a book as you describe, I wouldn't recommend it to people who are starting out with Book of Proof since they wouldn't be close to understanding the harder proofs, and I probably wouldn't recommend it to someone like a mathematician because they likely wouldn't need unrelated proofs all in one place. – Mark S.

    You'll need a book on Euclidean Geometry, Abstract Algebra, and Analysis to cover all these topics. If you're willing to drop the Pythagorean theorem you can replace it with complex analysis since it will cover all the trigonometry from a different perspective. I started with the Dover paperbacks because they're cheap. – CyclotomicField Oct 29 '22 at 14:48
  • H. Dorrie : 101 Great Problems In Elementary Mathematics 2. Courant & Robbins : What Is Mathematics? 3. Coxeter : Introduction To Geometry 4. Hobson : Trigonometry 5. Ahlfors : Complex Analysis, An Introduction.......

  • this is a text used in several introductory courses I'm aware of https://philarchive.org/rec/FRAPIM-2 – user24142 Nov 18 '22 at 09:06
