Question

(2*sinx+√2)/(2*cosx-√2)=0

Answer 1

$frac{2sinx+sqrt2}{2cosx-sqrt2} =0; ; to ; ; left { {{2sinx+sqrt2=0} atop {2cosx-sqrt2ne 0}} right. ; ,; left { {{sinx=-frac{sqrt2}{2}} atop {cosxne frac{sqrt2}{2}}} right. \\\ left { {{x=(-1)^{n+1}frac{pi}{4}+pi n; ,; nin Z} atop {x=pm frac{pi}{4}+2pi k; ,; k in Z}} right. ; ; to ; ; x=-frac{3pi }{4}+2pi n; ,; nin Z$
