Look at the attached figure. We define the unit circle as a circle with center 
in the origin (0,0) and radius 1.
Then, we consider a point P on the circumference. We call 
the angle between the positive half of the x axis and the radius AP.
We define
As you can see, ACD is a right triangle, and so we have
But since we know that AD is the cosine, AC is the sine, and AP is the radius (which is 1, and remains 1 when squared), we have just found out that
Answer:
Step-by-step explanation:
To find the slope of the line that passes through the points
<u>We have to follow the formula:</u>

When doing vertical subtraction, 800 - 675 will turn out like this:
800
- <u>675
</u><u>
</u>You should know that we start on the right and then end on the left.
<u>
</u>So, we do 0 - 5, 0 - 7, then 8 - 6, right?
No. We have to borrow because you can't have a negative number when doing each number individually, only until the end. In this case, there won't be any negative numbers.
<u>
</u>You can't do 0 - 5 or 0 - 7, so you have to borrow, changing the number to the left of it one lower (unless it's 0, so then you must borrow the the next number after that).<u>
