Using the addition rule of the Sine function and the Cosine function, we obtain .
<h3>What are the formulas for (sin x + sin y) and (cos x + cos y)?</h3>
- The formula for the addition of two Sine functions () is .
- The formula for the addition of two Cosine functions () is .
Given that
Then using the above formulas, we get:
(1)
(2)
Dividing the equation (1) by (2), we get:
(3)
Now, we know that .
Thus, using the above formula, we get from (3):
Therefore, using the addition rule of the Sine function and the Cosine function, we obtain .

Number one is B, because if you do the equation 2.94(total price)/ 7(number of items) it gives you the answer $0.42 then for number two A=$1.8 B=$1.83 C=1.81 and D=1.82 leaving A with the best price per bottle of juice. Hope this helped!
