The period is any rational number because if x is rational and d is rational then f(x+d)=f(x) =1 if x is irrational then x+d is irrational and f(x+d)=f(x)=-1 if d is irrational then x+d may be rational or irrational s the period is any rational number only

a and b rationals and 4-sqrt3 is a root of the equation then 4+sqrt 3 is a root -b/a =8 and 1//a=13 a=1/13 and b=-8/13

dx/(1+2e^(-x))= -tan y dy e^x/(e^x+2) dx = -tan ydy by integrating both sides ln (e^x+2)=_ln (cos x)+ln c e^x+2=c cos x e^0 +2= c /sqrt 2 c=3 sqrt 2 the answer is C
