+62 Can some explain to me how:
√−1=i
and how do you work out the sqaure root of -1?
+118703 Hi Nathan,
i is the basic unit of the imaginary number system.
Nothing multiplied by itself can be negative. That is impossible in the REAL world.
So √−1 does not exist in the real world.
BUT there is a whole other system of numbers called imaginary OR complex numbers and in that system
√−1 is assigned the letter i
