I think you just have to rewrite it to
-1.46×10^-7
Are 2,3,4,5,6,7,8,9 your welcome
-2x^3 = 0
solving for x you divide both sides by -2
x^3 = 0
Now take the cube root of each side
x = cube root of zero
x = 0
It has 1 root.
The root is zero
Answer:

Step-by-step explanation:
The cotangent of theta is:

For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:

In this question

So

Using cross multiplication



Now we apply the following trigonometric identity:






Since the angle is in the second quadrant, the sine is positive.

Finally, the cotangent:



1.
has a horizontal asymptote at 
This means that

(for at least one of these limits)
2.
has a vertical asymptote at 
This means that
has a non-removable discontinuity at
. Since
is some rational function, there must be a factor of
in its denominator.
3.
has an
-intercept at (1, 0)
This means
.
(a) With

the second point above suggests
. The first point tells us that

In order for the limit to be 0, the denominator's degree should exceed the numerator's degree; the only way for this to happen is if
so that the linear terms vanish.
The third point tells us that

So

(b) Since

we find that
, and
and
.
