2.57*10^4 is 1,000,000 times more than 2.57*10^-1

Why?

4-(-1)=5 2

2.57*10^4=25700

2.57*10^-1=0.0257

and

25700

÷ 0.0257

=1000000

and 1000000=10^6

Find all solutions to the equation (sinx-cosx)^2=1

svetoff [14.1K]

Answer:

$x=\dfrac{\pi k}{2},\ k\in Z.$

Step-by-step explanation:

Simplify the equation $(\sin x-\cos x)^2=1:$

$\sin^2 x-2\sin x\cos x+\cos ^2x=1,\\ \\ (\sin^2x+\cos^2x)-2\sin x\cos x=1.\\$

Since

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

and

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

we have

$1-\sin 2x=1,\\ \\\sin 2x=0,\\ \\2x=\pi k,\ k\in Z,\\ \\x=\dfrac{\pi k}{2},\ k\in Z.$
