Question

sinx cosx =1/2 then sinx-cosx=?​

Answer 1

given

sinx cos X = 1/2

$\sin(x) - \cos(x) = \sqrt{( \sin(x) - \cos(x) ) {}^{2} }$

then ,

I hope it help you

Answer 2

Answer

$\sin(x) \cos(x) = \sqrt{( \sin(x) - \cos(x)) } ^{2} \\\\ = \sqrt{ { \sin(x) }^{2} + { \cos(x) - 2 \sin(x) \cos(x) }^{2} } \\ \\ = \sqrt{1 - 2 \times \frac{1}{2} } \\ \\ = \sqrt{1 - 1 } \\ = 0$
