Question

sin(2pi-x)=0 give me a hand pls

Answer 1

Do you know for what values of u make sin(u)=0?

Answer 2

when the angle is 0 or 180

Answer 3

to radian, they are 0 and pi, right?

Answer 4

first, consider 0, that means sin (2pi -x) = sin (0) or 2pi-x = 0 so, x = 2pi, right?
second, consider pi, that means sin(2pi-x) = sin (pi) or 2pi -x = pi , x = 2pi -pi = pi, right?
does it make sense?
