[SOLVED] Solving csc x + 2 for 0
"Solve csc x + 2 = 0 for 0 <= x < 2 [tex]\pi[/tex]
Choices are:
A. [tex]\pi[/tex]/6 and 5[tex]\pi[/tex]/6
B. [tex]\pi[/tex]/6 and 7[tex]\pi[/tex]/6
C. 4[tex]\pi[/tex]/3 and 5[tex]\pi[/tex]/3
D. 7[tex]\pi[/tex]/6 and 11[tex]\pi[/tex]/6
csc x =2
sin x = 1/2 = 30 degrees = [tex]\pi[/tex]/6
From csc x + 2 = 0
I get csc x = 2
Which is:
1/sin = 1/2 and I know that 1/2 is [tex]\pi[/tex]/6
So the answer is either A or B but I don't understand where the second answer comes from.
