Does csc(-120)= -csc(120)
5 months ago
Q:
does csc(-120)= -csc(120)
Accepted Solution
A:
Answer:Yes!Step-by-step explanation:Using the unit circle, we find out that csc(120) = 2/[tex]\sqrt{3}[/tex] and csc(-120) = - 2/[tex]\sqrt{3}[/tex] . So, -csc(120) = -2/[tex]\sqrt{3}[/tex] . Note that -120 degrees is actually 240 degrees
