## IMSINH function

Returns the hyperbolic sine of a complex number. The hyperbolic sine of a complex number can be expressed by:

sinh(a+bi)=sinh(a)cos(b)+cosh(a)sin(b)i

IMSIN (\ "Númerocomplexo")

Complex_number is a complex number whose hyperbolic sine needs to be calculated.

=IMSINH("4-3i")

returns -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.
