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.
