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.

The answer is between B and C.

There are two different versions of standard deviation. The population standard deviation will use the formula shown in choice C, while the sample standard deviation uses the formula in choice B.

The instructions arent fully clear which your teacher wants. I would ask them for further clarification. I'm sorry I'm not more helpful.
