Diagonal theorem.
The Cantor diagonal method, also called the Cantor diagonal argument or Cantor's diagonal slash, is a clever technique used by Georg Cantor to show that the integers and reals cannot be put into a one-to-one correspondence (i.e., the uncountably infinite set of real numbers is "larger" than the countably infinite set of integers ).
Review Eigenvalues and Eigenvectors. The first theorem about diagonalizable matrices shows that a large class of matrices is automatically diagonalizable. If A A is an n\times n n×n matrix with n n distinct eigenvalues, then A A is diagonalizable. Explicitly, let \lambda_1,\ldots,\lambda_n λ1,…,λn be these eigenvalues.Polska Akademia Nauk.

The sentences whose existence is secured by the diagonal lemma can then, in turn, be used to prove fundamental limitative results such as Gödel's incompleteness theoremsFirst, we can use the Pythagorean Theorem to find the length of the second diagonal. 90 2 + 90 2 = d 2 8100 + 8100 = d 2 16200 = d 2 d = 127.3. This means that the diagonals are equal. If the diagonals are equal, the other two sides of the diamond are also 90 feet. Therefore, the baseball diamond is a parallelogram.

Theorem: the diagonalization theorem (two variants).Cantor shocked the world by showing that the real numbers are not countable… there are “more” of them than the integers! His proof was an ingenious use of a proof by contradiction. In fact, he could show that there exists infinities of many different “sizes”! Use the Pythagorean theorem to determine the length of X. Step 1. Identify the legs and the hypotenuse of the right triangle . The legs have length 6 and 8. X is the hypotenuse because it is opposite the right angle. Step 2. Substitute values into the formula (remember 'C' is the hypotenuse). A 2 + B 2 = C 2 6 2 + 8 2 = X 2.
Here’s how this theorem applies to squaring a foundation. Say you are laying the foundation of a square room with 10-foot long walls on each side. Think of the room as two separate right triangles. The diagonal that cuts across the room, and which forms the hypotenuse of the triangles, should be 14.142 feet: 102+102=200.
