If π/4 < x < π/2, Then Find the Value of √(1 − sin 2x)
Question
If
\[
\frac{\pi}{4}
Using the identity
Therefore,
Since
Solution
Hence,
\[ |\sin x-\cos x| = \sin x-\cos x \]Therefore,
\[ \sqrt{1-\sin2x} = \sin x-\cos x \]
If
\[
\frac{\pi}{4}
Using the identity
Therefore,
Since
Solution
Hence,
\[ |\sin x-\cos x| = \sin x-\cos x \]Therefore,
\[ \sqrt{1-\sin2x} = \sin x-\cos x \]
