    Simplify trig expressions: cos-1(cos(47pi/12), arcsin(tan(-pi/6)), csc-1(cos(2017pi/2

    1. cos-1(cos(47pi/12)
    2. arcsin(tan(-pi/6))
    3. csc-1(cos(2017pi/2018))
    4. cot(arcsin(1/2 csc(-11pi/4)))

    Those sure are some very nice homework problems you have there. But given that this is a tutoring website (note that the name is "Free Math Help," not "Free Homework Solutions" ), we'd like to see what you've done so far. So, what are your thoughts? What have you tried? Please re-read the Read Before Posting thread that's stickied at the top of each subforum and comply with the rules found within. Particularly, please share with us any and all work you've done on this problem, including the parts you know for sure are wrong. Thank you.

    This expression contains an inverse function. Have you learned what an inverse function does?
