Hi I have a parametrisation of the unit circle(adsbygoogle = window.adsbygoogle || []).push({});

z = cos(t) + isin(t) = e^(it)

now i guess that the conjugate of that is the same but with a negative coefficient on the imaginary part, namely:

conj z = cos(t) - isin(t)

How does that extend to the e^(it) form? is the following true:

cos(t) - isin(t) = e^(-it)

Thanks
