(cos A + cos b)^2 + (sin A + sin B)^2=?
emmasim [6.3K]
First, we expand the equation:

cos^{2}A+2cosAcosB+ cos^{2}B+sin^{2}A+2sinAsinB+sin^{2}B

Then, we combine certain terms in order to simplify them using trigonometry identities.

cos^{2}A+sin^{2}A+cos^{2}B+sin^{2}B+2cosAcosB+2sinAsinB

Note these identities:
Pythagoran relation: cos^{2}A+sin^{2}A = cos^{2}B+sin^{2}B=1
Sum and Difference Formula/Identities: cos(A-B) = cosAcosB+sinAsinB

Thus, if we apply these identities, the simplified equation would be:
2(cos(A-B))+2

Simplying further, the answer would be

2[cos(A-B)+1]

You bought 8 gumdrops for 2¢ apiece. For the same amount of money, how many gumdrops can you buy at 8¢ apiece? gumdrops
ser-zykov [4K]
First, how much did you spend on the 8 gumdrops at 2 cents a piece?

8 gumdrops at 2 cents a piece is 16 cents
8 gumdrops x 2 cents = 16 cents

So, if you have 16 cents to spend on gumdrops and they are 8 cents a piece, how many can you buy?
16 / 8 = 2

You can buy 2 gumdrops for the same amount of money.
