When Ф lies in quadrant IV the value of cos Ф lies in [0, 1].
<h3>What is quadrant?</h3>
One fourth of the part of a circle is said to be the quadrant of the circle.
Given the angle Ф lies in quadrant IV.
As we know, cos Ф is positive only in first and fourth quadrant i.e when Ф lies in 0<Ф<90 and 270<Ф<360.
cosФ range from [-1,1]
So, cos Ф is positive when Ф lies in 1st and 4th quadrant.
& cos Ф is negative when Ф lies in 2nd and 3rd quadrant.
If cos ∅ lies in the quadrant IV, anything between [0, 1] can be the value of cos ∅.
Hence, when Ф lies in quadrant IV the value of cos Ф lies in [0, 1].

Simplifying: ax + 6 = 14
Reorder the terms: 6 + ax = 14
Solving: 6 + ax = 14
Solving for variable 'a'.
Move all terms containing a to the left, all
other terms to the right. Add '-6' to each side of the equation.
6 + -6 + ax = 14 + -6
Combine like terms: 6 + -6 = 0
0 + ax = 14 + -6 ax = 14 + -6
Combine like terms: 14 + -6 = 8 ax = 8
Divide each side by 'x'.
a = 8x-1
Simplifying: a = 8x-1
