## anonymous one year ago Please help! Simplify the expression using a double angle formula and or half angle formula. Sin2*\1+cos2* (* means degrees)

1. DanJS

this may help for reference if you want to save it...

2. DanJS

are those sin^2(angle) or sin(2*angle)

3. DanJS

and is the [ 1 + cos2*] all in the denominator as a quantity, or is it just sin over 1, then plus cos

4. jdoe0001

$$\bf \cfrac{sin^2(\theta)}{1+cos^2(\theta)}?$$

5. DanJS

could see which combo comes out "nicer looking" since it is prolly a book prob.... nah

Its sin 2 degrees (not squared) over 1+ cos 2 degrees (not squared)
