How imaginary unit works in our real life
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 ... Web20 apr. 2024 · Imaginary Numbers, Real Uses.
