and also ELI16 what a an imaginary number is and how it works in real life
In: Mathematics
Imagine you have a puzzle, and some pieces are missing. Real numbers are like the pieces we can easily find and use. But sometimes, we need a special piece that doesn’t seem to fit anywhere at first. This special piece is the imaginary number “i.”
When we say we “make up” numbers like “i,” it’s because we need them to solve certain puzzles (math problems) that real numbers alone can’t solve. For example, if you have a problem where you need to find the square root of -1, real numbers don’t have an answer for that. But if we use “i,” we can say the answer is “i”.
Even though it sounds like we’re making things up, using imaginary numbers helps us solve real-world problems in fields like engineering, physics, and computer science. So, it’s like adding a new piece to our puzzle collection to complete more challenging and interesting puzzles.
