The completely factored form of the Wen's polynomial, which has the four terms initial, is,
<h3>What is the factor of polynomial?</h3>
The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.
Wen is factoring the polynomial, which has four terms.
'
Take out the greatest common factor from the equation and make separate groups as,
Rearrange the above equation as,
Thus, the completely factored form of the Wen's polynomial, which has the four terms initial, is,

At this case it could be calculated like this: 7+5*20=107
Answer: -1/2 or -0.5.
Explanation: -2- -1, -6- -2= -0.5
Answers:
- sin(C) = 24/25
- cos(Z) = 5/13
=============================================
Explanation:
The formulas we use are
- sin(angle) = opposite/hypotenuse
- cos(angle) = adjacent/hypotenuse
The fraction 15/39 reduces to 5/13 after dividing both parts by the GCF 3.
Answer:
Step-by-step explanation:
It is convenient to memorize the trig functions of the "special angles" of 30°, 45°, 60°, as well as the way the signs of trig functions change in the different quadrants. Realizing that the (x, y) coordinates on the unit circle correspond to (cos(θ), sin(θ)) can make it somewhat easier.

<h3>20.</h3>
You have memorized that cos(x) = (√3)/2 is true for x = 30°. That is the reference angle for the 2nd-quadrant angle 180° -30° = 150°, and for the 3rd-quadrant angle 180° +30° = 210°.
Cos(x) is negative in the 2nd and 3rd quadrants, so the angles you're looking for are
150° and 210°

<h3>Bonus</h3>
You have memorized that sin(π/4) = √2/2, and that cos(3π/4) = -√2/2. The sum of these values is ...
√2/2 + (-√2/2) = 0

<em>Additional comments</em>
Your calculator can help you with both of these problems.
The coordinates given on the attached unit circle chart are (cos(θ), sin(θ)).
