Repeating Pattern of Powers of i : | ||
---|---|---|

i0 = 1 | i4 = i3 • i = (-i) • i = -i2 = 1 | i8 = i 4• i4 = 1 • 1 = 1 |

i1 = i | i5 = i 4• i = 1 • (i) = i | i9 = i 4• i 4• i = 1 • 1• i = i |

i2 = -1 | i6 = i 4• i2 = 1 • (-1) = -1 | i10 = (i 4)2 • i2 = 1 • (-1) = -1 |

i3 = i2 • i = (-1) • i = -i | i7 = i 4• i3 = 1 • (-i) = -i | i11 = (i 4)2 • i3 = 1 • (-i) = -i |

## Can you simplify an imaginary number?

A simple shortcut to simplify an imaginary unit raised to a power is to divide the power by 4 and then raise the imaginary unit to the power of the reminder. For example: to simplify j23, first divide 23 by 4. 23/4 = 5 remainder 3.

**Which is the formula for an imaginary number?**

Imaginary numbers are based on the mathematical number i . From this 1 fact, we can derive a general formula for powers of i by looking at some examples. You should understand Table 1 above . Table 1 above boils down to the 4 conversions that you can see in Table 2 below.

**Which is the power of the imaginary unit I?**

Powers of i The imaginary unit i is defined as the square root of − 1. So, i2 = − 1. i3 can be written as (i2)i, which equals − 1(i) or simply − i.

### Is there a formula for powers of I?

From this 1 fact, we can derive a general formula for powers of i by looking at some examples. You should understand Table 1 above . Table 1 above boils down to the 4 conversions that you can see in Table 2 below. You should memorize Table 2 below because once you start actually solving problems, you’ll see you use table 2 over and over again!

### What are complex numbers and powers of I?
