Ok i have some homework probs due and, 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.I DO NOT WANT YOU TO DO THE WORK FOR ME

Thanks

Solve:

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

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

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

Evaluate:

4. $\displaystyle \sec(\arctan(-\frac{3}{5}))$

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

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