It was introduced by Joseph Fourier in the early 19th century and is widely used in mathematics and applied sciences. Although the Fourier series has infinitely many terms, it converges to the original function under certain conditions. This convergence process makes it possible to simplify complex prob

The special thing about this arrangement is the result: the sum of each row is the cube of its row number. The first row is 1, which is equal to 1 to the power of 3. The second row with 3 plus 5 is 8, which is equal to 2 to the power of 3. In the third row, 7, 9 and 11 add up to 27, the cube of 3. This pattern continue
