    2)Tan
    3)Sin
    4)ln
    5)e^x
    6) e^-x

    Thanks!

    1) -sin
    2) sec^2
    3) cos
    4) 1/x
    5) e^x
    6) -e^-x

    1) -sin(x)
    2) sec^2(x) (sec is 1/cos)
    3) cos(x)
    4) 1/x
    5) e^x (This is why we usually use powers of e, is simplifies differentiation and integration)
    6) -e^-x

    1) -sin(x)
    2) sec^(x) (sec is 1/cos)
    3) cos(x)
    4) 1/x
    5) e^x (This is why we usually use powers of e, is simplifies differentiation and integration)
    6) e^-x

    Incorrect. You ought to be careful on here, if you don't know it's 100% right then don't post...you could cost somebody their grades.

    Alternatively, that person could take the initiative to look up the differentials in a textbook. Then this wouldn't be an issue! These are all standard differentials that could be found in any book.

    :yep:
    It's exactly what I did before submitting the post, just to double check.
