I am looking for the fifth roots of unity, which I believe come in the form of:

cos(2kpi/5) + isin(2kpi/5), k=1,2,3,4,5 and when k=5, the complex number is 1.

how do you convert the rest to complex numbers? Normally, I use common triangles like:

45-45-90 and 30-60-90

but I don't think there is a triangle for 2pi/5.
