Question

 sinx/1-cosx=0

sin2x-корень3sinx=0

 

Answer 1

1)!= - не равен

$frac{sinx}{1-cosx}=0\ left { {{sinx=0} atop {cosx!=1}} right.\ x=pi+2pi k k in Z$

 

Ответ:{$pi+2pi k|k in Z$}

 

2)

$sin2x-sqrt3sinx=0\ sinx(2cosx-sqrt3)=0\ \ sinx=0 cosx=frac{sqrt{3}}{2}\ x=pi k k in Z x=(+|-)frac{pi}{6}+2pi l l in Z$

 

Ответ:{$pi k ; (+|-)frac{pi}{6}+2pi l|k,l in Z$}
