Find the quotient
3[cos5pi/12+isin5pi/12] divided by 6[cospi/12+isinpi/12]. Express the quotient in rectangular form.
I worked it out as:
Is this right?

You started out OK but went astray somewhere.
Here's one way to do it.
Rewrite it as
= (1/2)[cos (pi/3)+ i sin(pi/3)]
You got that far..
= (1/2)[(1/2) + i(sqrt3)/2]
1/4 + i (1/4)* sqrt3
