Can you solve sin(x)=0?Not sure on how they got the other two solutions (inside the drawn red square) - please refer to my attachments.
x = 0, pi, 2pi ??Can you solve sin(x)=0?
x is any real number.
Any other solutions? Have you seen a sin(x) graph? Did you notice how it keeps intersecting the x axis as it extends to the right _and_ left? What does it tell you about the solutions of sin(x) = 0?x = 0, pi, 2pi ??
Those are answers only for one period of a sine graph. The sine graph goes well beyond [0, 2pi)x = 0, pi, 2pi ??
OH WAIT!!! I did not consider the domain properly.... Thank you!! I get it nowWe know that for one period of a sine cure that 0<= x <=2pi, so 0<= 2x < 4pi
