IMTAN function

Returns the tangent of a complex number.

The tangent of a complex number can be expressed by its real and imaginary parts:

\tan (a + bi) = \frac{\sin (2 a) + i \sinh (2 b)}{\cos (2 a) + \cosh (2 b)}

The result is presented in the string format and has the character "i" or "j" as an imaginary unit.

See funktsioon on saadaval alates LibreOfficeDev 3.6-st.

Süntaks

IMSIN("kompleksarv")

Complex_number is a complex number whose tangent is to be calculated.

A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers.

If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.

Näited

=IMTAN("4-3i")
returns 0.00490825806749606-1.00070953606723i.

=IMTAN(2)
returns -2.18503986326152 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
