its not a st. line so no question about this. it has infinite no of solution when y=0 sin2x=0 x=npi/2
OpenStudy (anonymous):
ok, what are the x-intercepts in the domain of 0-2pi
OpenStudy (anonymous):
then it is 0,pi/2, pi,3pi/2, 2pi
OpenStudy (anonymous):
if the domain is (0,2pi) instead of [0,2pi] then u have to exclude the terms 0 and 2pi
OpenStudy (anonymous):
i think u are enough intelligent to understand this.
