Answer:
Integers are not closed under the DIVISION operation
Example:
(9 ÷ 2 = 4½)
Answer:
a =
and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 = 
So: a =
and b =
That relationship can be expressed by either of ...
You are adding two each time
3 radical 70. 9 times 70 is 630, 9 squared is 3.
