Answer:
Step-by-step explanation:
- cotx cos x - cot x = 0
- cotx( cosx - 1) = 0
1. <u>cotx = 0</u>
- x = π/2 + πn
- In the interval [0, 2π] we have π/2 and 3π/2
2. <u>cosx = 1</u>
- x = 0 + 2πn
- In the given interval we have 0 and 2π
<u>So the solution set is:</u>

Answer:
15/17
Step-by-step explanation:
Sine is 
, and we see that the angle opposite of A is 15 while the hypotenuse is 17. Plug that into your formula and you get

Answer:
it should be x=4
Step-by-step explanation:
The line that is perpendicular to
y
=
−
3
is a horizontal line, because horizontal and vertical lines (
x
- and
y
- axes for example) are perpendicular. Therefore, this line will take the form
x
=
n
where
n
is the
x
-coordinate of the point passed through. The
x
-coordinate of the given ordered pair
(
4
,
−
6
)
is
4
, so the equation must be
x
=
4
