Best ResponseYou've already chosen the best response.0set the y's equal...: sin2x = sinx given 2sinxcosx = sinx use the double angle formula for sine 2sinxcosx  sinx = 0 move the sinx over to the left side sinx(2cosx  1) = 0 factor can you do the rest from here?

Best ResponseYou've already chosen the best response.0ok... the interval is [0, 2pi]

Best ResponseYou've already chosen the best response.0so from the last equation: sinx(2cosx  1) = 0 you'll need to set each factor equal to zero... sinx = 0 solve this... and also 2cosx  1 = 0 solve this....

Best ResponseYou've already chosen the best response.0in the first equation, what angle between 0 and 2pi will give you a sine of zero?
