The 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)

PartDescriptionNotes
numberThe 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.

4=IMSEC("3+2i")

IMCOS:  The IMCOS function returns the cosine of the given complex number.

IMSECH:  The IMSECH function returns the hyperbolic secant of the given complex number.

COMPLEX: The COMPLEX function creates a complex number, given real and imaginary coefficients.
