What Are Imaginary Numbers? Live Science

WebThe imaginary unit i i is a number that is not a real number. The real number system \mathbb {R} R is extended to the complex number system \mathbb {C} C taking i i into account: \mathbb {C} = \ { a + bi a,b \in \mathbb {R} \}. C = {a+bi∣a,b ∈ R}. The definition of i i is quite ambiguous. i i is "a" solution to the quadratic equation x^2 ... WebThe imaginary unit i i allows us to find solutions to many equations that do not have real number solutions. This may seem weird, but it is actually very common for equations to be unsolvable in one number system but solvable in another, more general number system. … Why is this significant?
