Best Answer

i is equalled to the square root of -1.

The square root is a number which, multiplied by itself, will give a number (eg: 2 is the square root of 4 because 2x2=4)

But negative numbers can't have square roots because any number multiplied by itself will be positive.

So 'i' is imaginary.

You use 'i' in calculus to figure out complex problems.
