    Reassurance

    Ok i have some homework probs due and I DO NOT WANT YOU TO DO THE WORK FOR ME, i can do it on my own. However, it would be cool if someone could post up the answer so I can double check my work after i finish (i just got them and am going to work on them tonight). I have to show all my work so posting just the answer will only be for my reassurance that i've done the problems correctly. If i get a wrong answer and can't figure it out my error then i'll post up my steps and ask for further assistance.
    Thanks

    Solve:
    1. \int[(x-1)^2(x^2-2x)]^\frac{1}{2}dx

    2. \int\frac{dx}{2\sqrt{(3-x)(x+1)}}

    3. \int[\sqrt{1+(x+1)^2}]^{-1}

    Evaluate:
    4. \sec(\arctan(-\frac{3}{5}))

    5. \frac{d}{dx}[\ln(x^2+4)-\frac{1}{2}\tan^{-1}(\frac{x}{2})]

    6. \frac{d}{dt}\sec^{-1}(\csc(2t^2-\ln t))
