IMPRODUCT(z1,z2,z3)
- are the complex numbers of the form
- is the power value.
are the complex numbers of the form 
is the power value.Description
- This function gives the value of powers of complex number.
- DeMoivre's Theorem is a generalized formula to compute powers of a complex number in it's polar form.
- i'is the imaginary unit, .
- Then the power of a complex number is defined by Failed to parse (syntax error): {\displaystyle (z)^n=(x+iy)^n=r^n*e^inθ=r^n(cosnθ+isinnθ)} where and Failed to parse (syntax error): {\displaystyle θ=tan^-1(y/x)} , θ∈(is belongs to) (-Pi(),Pi()].
- This formula is called DeMoivre's theorem of complex numbers.
- We can use COMPLEX function to convert real and imaginary number in to a complex number.
- In IMPOWER(z,n), n can be integer, fractional or negative.
- suppose n is nonnumeric , this function will returns the error value.
