Check this for me please involving sin theta
For sin theta= -0.4321, 0<=theta<=2pi
QUESTIONS
a) How many solutions are possible?
b)In which quadrants would you find the solutions?
c)Determine the reference angle for this equation to the nearest degree.
d) Determine all the solutions to the equation to the nearest degree
MY ANSWERS
a) 2
b) quadrants 3 and 4
c)-26 degrees (im not sure if the negative should be there)
d)solutions theta=334 degrees and theta=206 degrees
Can someone please check to see if I am on the right track please
