Find all solutions to the equation (sinx-cosx)^2=3

Karo-lina-s [1.5K]

Answer:

no solutions

Step-by-step explanation:

Simplify the equation $(\sin x-\cos x)^2=3:$

$\sin^2 x-2\sin x\cos x+\cos ^2x=3,\\ \\ (\sin^2x+\cos^2x)-2\sin x\cos x=3.\\$

Since

$\sin^2 x+\cos^2 x=1$

and

$2\sin x\cos x=\sin 2x,$

we have

$1-\sin 2x=3,\\ \\\sin 2x=-2.$

Since $\sin 2x$ cannot be less than $-1,$ this equation has no solutions.
