IMSIN
Returns the sine of a complex number.
This function is only available if the Analysis AddIn is installed.
Syntax:
IMSIN(complexnumber)
- complexnumber is text representing a complex number, for example as a+bi or a+bj.
- IMSIN returns the sine of complexnumber, as text - that is, if complexnumber is a+bi, it returns sin(a)cosh(b)+cos(a)sinh(b)i.
Example:
IMSIN("2+3i")
- returns 9.15449914691143-4.16890695996656i as text.
Issues:
- This function currently appears in the AddIn category of the Function Wizard.
