and also ELI16 what a an imaginary number is and how it works in real life
In: Mathematics
Basically mathematicians were trying to figure things out but at some point in calculation they encountered a part where that had √-1 which can’t be solved since any number squared ends up being positive so they just went like “well let’s imagine there was a number that when squared equals -1” and they called that number “i” so “i = √-1” and whenever they found √-1 on their work they just substituted it for i, but then how do you solve the equations and apply the in real life if you have to use a number that doesn’t exist? Well luckily later in the equations there was a point when they had to square i so they end up with just -1 which is a regular number so the problem solves itself.
