How to Use IMSEC function in Google Sheets in 2020?

IMSEC functionThe IMSEC function returns the secant of the given complex number. For example, a given complex number “x+yi” returns “sec(x+yi).”

Parts of an IMSEC function

IMSEC(number)

Part
Description
Notes

number
The complex number for which you want the secant.
This can be either the result of the COMPLEX function, a real number interpreted as a complex number with imaginary parts equal to 0, or a string in the format “x+yi” where x and y are numeric.

Sample formulas

IMSEC(COMPLEX(4,6))

IMSEC(4)

IMSEC(“2+3i”)

Notes

The IMSEC function returns an error if the given number isn’t a valid complex number.
