1/2 : 1
2 : 4
3 : 6
Notice that every ratio consists of a number and double the number.
For 1/2 cup lemon juice, use 1 cup sugar.
The amount of sugar is twice the amount of lemon juice.
The ratio is 1:2
Since you are told the ratio is 1:r, that means r is 2.
The unit rate is 2 cups sugar per cup of lemon juice.

Answer:
![\sin \frac{3\pi}{2} = -1](https://tex.z-dn.net/?f=%5Csin%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%20-1)
![\cos\frac{3\pi}{2} =0](https://tex.z-dn.net/?f=%5Ccos%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D0)
Step-by-step explanation:
Please refer to the image attached.
Here we have a circle with unit radius. At some angle Ф the radius = 1 , and it is the hypotenuse (shown by green line in the image attached) of the ΔPQR thus formed. As our angle Ф increases, the hypotenuse gets closer to the positive y axis and at 90°, it overlap the y axis. Hypotenuse (H) and Opposite site (O) becomes same and Adjacent (A) becomes 0.
As our angle move further and reaches 180, the Hypotenuse and adjacent becomes same and overlap negative x axis. As we move further at 270 i.e
, the hypotenuse and opposite side overlap on y axis and Adjacent side become 0. However the opposite side becomes negative here .
Our sine ratio says
![\sin \frac{3\pi}{2} =\frac{opposite}{Hypotenuse}](https://tex.z-dn.net/?f=%5Csin%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%5Cfrac%7Bopposite%7D%7BHypotenuse%7D)
![\sin \frac{3\pi}{2} =\frac{-1}{1}](https://tex.z-dn.net/?f=%5Csin%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%5Cfrac%7B-1%7D%7B1%7D)
![\sin \frac{3\pi}{2} =-1](https://tex.z-dn.net/?f=%5Csin%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D-1)
Hence we have our ![\sin \frac{3\pi}{2} = -1](https://tex.z-dn.net/?f=%5Csin%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%20-1)
Now
![\cos\frac{3\pi}{2} =\frac{Adjacent}{Hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D)
Adjacent as we discussed is 0 at ![\frac{3\pi}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%7D%7B2%7D)
![\cos\frac{3\pi}{2} =\frac{0}{1}](https://tex.z-dn.net/?f=%5Ccos%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D%5Cfrac%7B0%7D%7B1%7D)
![\cos\frac{3\pi}{2} =0](https://tex.z-dn.net/?f=%5Ccos%5Cfrac%7B3%5Cpi%7D%7B2%7D%20%3D0)
