Review the proof step statement 1 cos(2x) = 1-sin^2(x)

ehidna [41]

Answer:

Option (3)

Step-by-step explanation:

Correct steps for the proof are,

Step Statement

1 cos(2x) = 1 - 2sin²(x)

2 Let 2x = θ

3 x = $\frac{\theta}{2}$

4 $\text{cos}\theta = 1 - 2\text{sin}^2(\frac{\theta}{2} )$

5 $\text{cos}\theta-1 =-2\text{sin}^2(\frac{\theta}{2} )$

6 $1-\text{cos}\theta =2\text{sin}^2(\frac{\theta}{2} )$

7 $\frac{1-\text{cos}\theta}{2} =\text{sin}^2(\frac{\theta}{2} )$

8 $\pm \sqrt{\frac{1-\text{cos}\theta}{2} }=\text{sin}(\frac{\theta}{2} )$

There is a mistake in step 6.

Therefore, Option (3) will be the answer.

An angle in standard position measures radians, and P(0, 1) is on the terminal side of the angle. What is the value of the cosin

lana [24]

Answer: 0

Explanation:

1) Cosine trigonometric ratio definition:

cos (α) = adjacent-leg / hypotenuse

2) P (0,1) ⇒

- adyacent-leg = x-coordinate = 0
- opposite-leg = y-coordinate = 1
- hypotenuse = √[x² + y² ] = 1

3) Therefore, cos(α) = 0 / 1 = 0
