    Check my answers? Trig/Derivative Problems?

    My professor sent out an online practice quiz, and I've answered all the questions but when I submit it it doesn't show me what I got right or wrong. It's not for an actual grade just participation points and I just want to make sure I'm doing them right? Are any wrong? I think I did well but I'm not sure because it won't even say! Thanks!

    If you are just looking to check your answers, I would recommend entering them into WolframAlpha.com. There are a LOT of problems there, and it seems like it is just as easy for you to plug them in as it would be for one of us.
