IMSIN(z)

• where z is any real number

## Description

• This function gives the sin 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.
• sin(x+iy) is defined by sin(x+iy)=sin(x)cosh(y)-icos(x)sinh(y)

## Examples

IMSIN(iz)

• iz is the complex number.
