How do you find the exact circular function value of csc(-23pi/6)? I don't know how to do the pi symbol on the keyboard.
first find the smallest positive coterminal angle to your given angle
-23π/6 = -24π/6 + π/6 --- >
so csc(-23π/6) = csc π/6
= 1/sin π/6
check with your calculator, (make sure you are set to radians)
