Answer:
(a) 1/2
Step-by-step explanation:
The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...
(x, y) = (cos(α), sin(α))
When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.
1/6
3/14
2/7
1/3
I think its like this
√x² - 4 + x²/x² + 1
x - 2 + x²/x² + 1
<u>x - 2</u> + <u> x² </u>
1 x² + 1
<u>(x - 2)(x² + 1)</u> +<u> x² </u>
(1)(x² + 1) x² + 1
<u>x³ + x - 2x² - 2</u> + <u> x² </u>
x² + 1 x² + 1
<u>x³ - 2x² + x² + x - 2</u>
x² + 1
<u>x³ - x² + x - 2</u>
x² + 1
x³ + x - 2
1a (you don’t necessarily need to include the 1, so you can just put “a” if you’d like).
