D complex numbers are tricky...

import std.stdio, std.math;
void main() {
    int kth = 3;
    auto wk1 = cos(kth);
    auto wk2 = cast(ireal) sin(kth);
    auto wk = wk1 + wk2;
    writefln(wk);

    auto wk3 = cos(kth) + sin(kth) * 1i;
    writefln(wk3);
}

It prints:
-0.989992+0i
-0.989992+0.14112i
