URGENT! Math Problem help needed for final!

I need to write this complex number in rectangular form:
z = 8(cos p/6 + i sin p/6)
Do I just distribute the 8 into the real and imaginary terms?
Like...
z = mag ( real + imaginary)
mag*real + mag*imaginary?
Thanks
Multiplication of two complex numbers z1 and z2 is defined as:
Writing 8 as the complex number z2 = (8,0i) and the original number z1=(cos p/6, sin p/6) we get:
So eventually it turns out right; you could have just distributed the 8. Greetz,

z1z2 = (x1,y1)(x2,y2) = (x1x2-y1y2, x1y2+x2y1)Writing 8 as the complex number z2 = (8,0i) and the original number z1=(cos p/6, sin p/6) we get:
(8,0)(cos p/6,sin p/6) = (8cos p/6-0sin p/6, 8sin p/6+cos p/6*0) =(8 cos p/6, 8 sin p/6 )So eventually it turns out right; you could have just distributed the 8. Greetz,

Whee! We've moved beyond doing people's homework for them to actively helping them cheat on test in real time! Isn't the Internet wonderful?
