# IMCSCH

Formulas / IMCSCH
Calculate the hyperbolic cosecant of a complex number.
`=IMCSCH(inumber)`
• inumber - a complex number required

## Examples

• `=IMCSCH("4+3i")`

The function in Sourcetable returns the inverse cosecant of a complex number, and would return 0.13815897. This means that the cosecant of 4+3i is 0.13815897.

• `=IMCSCH(5)`

The function can also be used to calculate the inverse cosecant of a real number, and would return 1.537475. This means that the cosecant of 5 is 1.537475.

• `=IMCSCH("-2i")`

The function can also be used to calculate the inverse cosecant of an imaginary number, and would return -1.5707963. This means that the cosecant of -2i is -1.5707963.

• `=IMCSCH("(1+2i)/(3-4i)")`

The function can also be used to calculate the inverse cosecant of a complex expression, and would return 0.11878894. This means that the cosecant of (1+2i)/(3-4i) is 0.11878894.

## Summary

The IMCSCH function calculates the hyperbolic cosecant of a complex number, taking the complex number as its argument.

• The IMCSCH function returns the hyperbolic cosecant of a complex number, which needs to be formatted as x+yi or x+yj.
• The inumber argument is required for the function to work, and it must be a complex number.
• The function will return a #VALUE! error if the inumber argument is a logical value.
