Summary

The Excel IMSINH function returns the hyperbolic sine of a complex number.

Purpose 

Get hyperbolic sine of the complex number.

Return value 

The hyperbolic sine of the complex number.

Syntax

=IMSINH(complex_num)
  • complex_num - The complex number in the form "x+yi".

How to use 

The Excel IMSINH function returns the hyperbolic sine of a complex number. For example, given 1+π/2i as input, the function returns -4.10319E-15 + 1.543080635i as output.

=IMSINH(COMPLEX(1, PI()/2)) // returns -4.10319E-15 + 1.543080635i

When the function's output is plotted over the complex plane, the real output along the real axis traces the shape of the SINH function.

=IMSINH(COMPLEX(x,0)) // returns SINH(x) + 0i

The imaginary output along the imaginary axis traces the shape of the SIN function.

=IMSINH(COMPLEX(0,y)) // returns 0 + SIN(y)i

Explanation

The function can be defined for complex input using the SIN, COSSINH, and COSH functions, which take real numbers as input.
