By De Moivre's theorem,
We can stop here ...

... but we can also express these trig ratios in terms of square roots. Let 
and let 
. Then recall that
On the left, 
so that
Since 
, we're left with
because we know to expect 
. Then from the Pythagorean identity, and knowing to expect 
, we get
Both 
and 
are 
-periodic, so that
and
so that the answer we left in trigonometric form above is equal to
Answer:
1- Do 12 times 5 and then 12 times 10. add the sums together
2-Do 15 times 2 and then 15 times 10. Add the sums together
3-You could split 12 in half to get two 6s. Do 15 times 6 and multiply the product by 2 to get your answer
