Find z/w in polar form, if z=4(cos 50 deg+i sin 50 deg),...

[Iknownothing17]

If z= 4(cos 50 degrees + i sin 50 degrees) and w= 2(cos 340 degrees +i sin 340 degrees) find z/w in polar form

is it 2[cos (-290 degrees) + i sin (-290 degrees)]

or is it

2(cos 290 degrees + i sin 290 degrees)?

I'm getting your first answer, but you probably should express the angles in terms of positive values. Note: -290 + 360 = 50. :wink:
