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.

  • Trig - ,

    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
    = 1/(1/2)
    = 2

    check with your calculator, (make sure you are set to radians)
