Question

2COS(X/2-ПИ/6)=КОРЕНЬ ИЗ 3

Answer 1

$2*cos(frac{x}{2} - frac{pi}{2} )=sqrt{3} \ cos(frac{x}{2} - frac{pi}{2} )=frac{sqrt{3} }{2} \ frac{x}{2} - frac{pi}{2}=frac{pi}{6} frac{x}{2}=frac{4pi}{6} x=frac{8pi}{6}=frac{4pi}{3}+2pi*n$

Answer 2

2cos($frac{x}{2} - frac{pi}{6}</var>)$ = <img src=[/tex]sqrt{3}" title="frac{x}{2} - frac{pi}{6})" title="sqrt{3}" title="frac{x}{2} - frac{pi}{6})" alt="sqrt{3}" title="frac{x}{2} - frac{pi}{6})" /> = $frac{x}{2} - frac{pi}{6}</var>)$ = $<var>sqrt{3}$

cos($frac{x}{2} - frac{pi}{6}</var>)$

cos($<var>sqrt{3}$

cos($frac{x}{2} - frac{pi}{6}</var>)$ = $frac{<var>sqrt{3}}{2}$ = $frac{x}{2} - frac{pi}{6}</var>)$ = $frac{<var>sqrt{3}}{2}" /></var></p> <p>[tex]frac{x}{2} - frac{pi}{6} = frac{pi}{6}$

$frac{x}{2} = frac{pi}{3}$

$x = frac{pi}{3} +2pi n$
