The IMPOWER
function returns a complex number raised to a power.
Parts of a IMPOWER formula
The IMPOWER
formula is formatted as =IMPOWER(complex_base, exponent).
Part | Description | Notes |
complex_base |
The complex number to raise to the exponent power. |
|
exponent |
The exponent to raise complex_base to. |
|
Sample formulas
IMPOWER("4-3i",0.5)
IMPOWER(A2,B2)
IMPOWER("2j",-7)
Notes
- The exponentiation of a complex number is defined as follows:
- (a+bi)n = rn(cosθ + isinθ), where
- r = √(x2 + y2) and θ = arctan(b/a)
