Cú pháp

IMSIN("Số_phức")

Complex_number is a complex number whose sine needs 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 complex number is actually a real number (b=0), then it can be either a string expression or a number value.

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.

Ví dụ

=IMSIN("4-3i")
returns -7.61923172032141+6.548120040911i.

=IMSIN(2)
returns 0.909297426825682 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
