Welcome to the principle of Fourier series.
Now, "wave" to trigonometric (circular functions) can be approximated by summing of the Fourier series from the principles and mechanisms, we can understand intuitively explained.
(The calculation does not only uses addition and subtraction and multiplication and fractions. Please believe in the power of your own intuition.)
<Year 1768 - 1830 Joseph Fourier>
"Trigonometric functions with (circular functions) represented by the sum of."
This idea, "Egypt's mysterious country" is likely to leave were obtained.
Accompanied Napoleon's expedition to Egypt, we made a mathematical study various archaeological years 1801 - 1798.
Take home to France to discover the Rosetta Stone at this time has seen the age of 12 was Champollion.
Speaking of ancient Egypt, Pythagoras endowed 思I浮Kabemasu a priest of the mysteries of time.
Egypt is the wisdom of the "Pythagorean theorem" Knowing, "Principles of Fourier series," I can understand.
Sure to cite the cycle (series) increases the overall resolution.
However, the Fourier series itself, the shape of the wave is not close.
Only minor variation of the wave (total) are close to but just.
On behalf of the wave position, the amount of change in a limited period if they are watching as a wave.
Rather than deterministic, but the convergence is in fact an agnostic.
(If you explore the Fourier series as a deterministic, Achilles and the Tortoise comes into the head.)
※ Fourier series, you have what looks like a wave of interest, I will never know.
Integration with Datte, has a total area of overlap. In the differential never that way.
