Convert the polar representation of this complex number into its standard form: z=8(cos240degrees + isin 240degrees)

Step-by-step explanation:

The standard form of a complex number is a + bi.  where

 and  

Putting these together to get the form that you have right now gives you

and you have the r factored out.  If you want to find out what a is then in a + bi, find out what 8cos(240) is on your calculator.  

8cos(240) = -4

Likewise for b:

8sin(240) = -6.9

Putting these together in standard form gives you -4 - 6.9i

y = i/2 xtnop + (3i/2 tnop+ 1)
