МНИМ.SINH(КомплексноеЧисло)
Complex_number is a complex number whose hyperbolic sine needs to be calculated.
=МНИМ.SINH("4-3i")
возвращает -27,0168132580039-3,85373803791938i.
=IMSINH(2)
returns 3.62686040784702 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
