IMCOS(iz)
- where 'iz' is the complex number
Description
- This function gives the cos value of 'iz'.
- Where iz is the complex number in the form of
- x & y are the real number
- 'i' is the imaginary unit
- Also x is called the real part & y is the imaginary patr of a complex number.
- 'COMPLEX' is the function used to convert real& imaginary numbers in to a complex number.
- cos(x+iy) is defined by cos(x+iy)=cos(x)cosh(y)-isin(x)sinh(y)
Examples
IMCOS(iz)
- iz is the complex number.
| IMCOS(iz) | Value(Radian) |
