Find all the solutions to the equation sin (theta) +1 = 0

write your answer in radians in terms of pi and use the "or" button as necessary
ex theta = ((2*pi)/(5)) +k*pi k semicircle with a line in the middle Z or
theta = ((8*pi)/5) +2k*pi, k semicircle with a line in the middle Z

PLEASE HELP i have totally confused by question

sin (theta) = -1
theta = 3pi/2 + 2n*pi, where n can be any integer.
