Evaluate arccsc 2 A. Pi/3
B. {Pi/3+-2Pi,5pi/3+-2pi
C. Pi/6,5Pi/6
D. Pi/6+-2Pi, 5Pi/6+-2Pi

The answer is option C

arccsc 2 = π/6 , 5π/6

Hope this helps

a is the correct

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
