Question

Part 2 of 4 To find cos( heta) = 0, sin( heta) = -1. The angle between 0 and 2pi is heta = frac{3pi}{2}. Part 3 of 4 Therefore -4i = 4(cos(frac{3pi}{2}) + i sin(frac{3pi}{2})) Part 4 of 4 Repeat the process instantly to write -64i in trigonometric form -64i =

          Part 2 of 4
To find cos(	heta) = 0, sin(	heta) = -1. The angle between 0 and 2pi is 	heta = frac{3pi}{2}.
Part 3 of 4
Therefore
-4i = 4(cos(frac{3pi}{2}) + i sin(frac{3pi}{2}))
Part 4 of 4
Repeat the process instantly to write -64i in trigonometric form
-64i =

$Part 2 of 4 To find cos( heta) = 0, sin( heta) = -1. The angle between 0 and 2pi is heta = frac3pi2. Part 3 of 4 Therefore -4i = 4(cos(frac3pi2) + i sin(frac3pi2)) Part 4 of 4 Repeat the process instantly to write -64i in trigonometric form -64i =$
