Using the identity :
Cos (2a) = 1-2 Sin^2(a)
Therefore :<span>1−2 sin ^2 (22.5∘) = Cos(2a)
= Cos (2 * 22.5) = Cos 45</span>
Answer:
<h3> a₁ = -1</h3>
Step-by-step explanation:
Answer:
0.24 its opposite value is - 0.24
1/4 its opposite value is -1/4
0
-5 its opposite value is 5
240 which is positive and its opposite value is -240
Step-by-step explanation:
hey
from the given statement we can see that question demand is about the opposite values. so
as our first value is 0.24 its opposite value is - 0.24
then move on next value is 1/4
its opposite value is -1/4
0 is a neutral value it neither positive or negative
move on to the next value which is -5 who is already negative
so we take a positive value that is 5
again move to 240 which is positive and its opposite value is -240
