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+iy".i.e.
- x&y are the real numbers.
- 'I' imaginary unit .i=sqrt(-1).
- 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) |
| IMCOS("2+3i") | -4.18962569-i9.10922789 |
| IMCOS("2-3i") | 4.18962569-i9.10922789 |
| IMCOS("2") | 0.4161468365471424 |
