<h2>Area of a square = side × side</h2>
Let the side = x

<h3>Length of each side = <u>8</u><u> </u><u>units</u></h3>
.... Hope this will help....
So, Cot is negative in second and fourth quadrant.
So, tan(x+
)=-cot(x)
Option B
Answer:
See proof below
Step-by-step explanation:
We will use properties of inequalities during the proof.
Let
. then we have that
. Hence, it makes sense to define the positive number delta as
(the inequality guarantees that these numbers are positive).
Intuitively, delta is the shortest distance from y to the endpoints of the interval. Now, we claim that
, and if we prove this, we are done. To prove it, let
, then
. First,
then
hence
On the other hand,
then
hence
. Combining the inequalities, we have that
, therefore
as required.
