sinx - cosx = √2
(sinx - cosx)2 = 2
sin2 x + cos2 x - 2sinx cosx = 2
1 - sin2x = 2
sin 2x = -1
Using formula ![begin mathsize 16px style sin 2 straight x space equals space fraction numerator 2 tanx over denominator 1 minus tan squared straight x end fraction end style](https://images.topperlearning.com/topper/tinymce/cache/e88357201dbedfe26d6c635173fa5ac7.png)
