Find all solutions to the equation.

Bess [88]

If the equation is

$7\sin^2x-14\sin x+2=-5$

then rewrite the equation as

$7\sin^2x-14\sin x+7=0$

Divide boths sides by 7:

$\sin^2x-2\sin x+1=0$

Since $x^2-2x+1=(x-1)^2$ , we can factorize this as

$(\sin x-1)^2=0$

Now solve for <em>x </em>:

$\sin x-1=0$

$\sin x=1$

$\implies\boxed{x=\dfrac\pi2+2n\pi}$

where <em>n</em> is any integer.

If you meant sin(2<em>x</em>) instead, I'm not sure there's a simple way to get a solution...

How do I solve this ?

eduard

Look at the picture.

ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:

$\dfrac{DC}{ZX}=\dfrac{DY}{ZY}$

DC = x

ZX = 16

DY = a

ZY = a + a = 2a

Substitute:

$\dfrac{x}{16}=\dfrac{a}{2a}$

$\dfrac{x}{16}=\dfrac{1}{2}$ <em>multiply both sides by 16</em>

$\boxed{x=8}$

<h3>Answer: CD = 8</h3>
