Basics of Iota
Iota originated with attempts to solve certain algebraic equations, such as x2 + 1 = 0
Iota stands for the square root of – 1.
Some values of iota that we should know.
Solving Powers of Iota
Step 1: Divide the power of iota by 4.
Step 2: The remainder left will now be the real power of iota. Forget the quotient; it is of no use now.
Step 3: Use the table above to calculate the value.
For ex.
To find values for in, where n > 4, we first divide n by 4, i.e. let n be a number of the form
n = 4m + r.
Then in = i4m+r= i4m × ir= ir
