It might have been a few years since trigonometry, but you will quickly realize that mastering the basics of trigonometry is essential for your success in electrical engineering. Sine functions are one [...]
Binary numbers work exactly like our decimal system. It’s called Decimal because it has 10 total combinations per digit. For instance we count 0-1-2-3-4-5-6-7-8-9 which gives us 10 total numbers we can use in a single digit. When we run out of digits we add one to the leading digit and switch the current digit [...]
