IMCOS प्रकार्य

Returns the cosine of a complex number. The cosine of a complex number can be expressed by:

cos(a+bi) = cos(a)cosh(b) - sin(a)sinh(b)i

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

वाक्य संरचना

IMCOS(जटिल सङ्ख्या)

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

द्रष्टव्य प्रतिमा

A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers.
If the complex number is actually a real number (b=0), then it can be either a string expression or a number value.


चेतावनी प्रतिमा

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


उदाहरणहरू

=IMCOS("4-3i")
returns -6.58066304055116-7.58155274274654i.

=IMCOS(2)
returns -0.416146836547142 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
