On the unit circle, the radius is 1. We found the coordinates of common angles such as 30°, 60°, 45°, and 90°. What would be the coordinates of a 22° angle? Round coordinates to the nearest hundredth. (Hint: Draw a picture and think of the unit circle stuff)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

$12. that is my answer.

a: 1/6, j: 1/4
