Answer:
sin²x
Step-by-step explanation:
we have
(1 − cos x)(1 + cos x)=1-cos²x
Remember that
sin²x+cos²x=1 ------> i-cos²x=sin²x
therefore
(1 − cos x)(1 + cos x)=sin²x
First, find what you can multiply by 
to get closest to (but not over) 
.
This value is 
.
Now, multiply 
to get 
.
Subtract 
to get a remainder of 
.
Answer:
1/4
Step-by-step explanation:
