I need answers quick Hi, I have a test tomorrow and I need to be able to Evaluate these integrals step by step. 1. $\int\frac{e^sqrt{x}}{sqrt{x}}dx$ 2. $\int_{e}^{e^2}x^3ln(x)dx$ 3. $\int\frac{x^2}{sqrt{16-x^2}}dx$ 4. $\int\frac{2}{x^2+1}dx$ 5. $\int\frac{x-2}{x^2-1}dx$ 6. $\int\frac{x^2-1}{x-2}dx$ 7. $\int tan^-^1(x)dx$ 8. $\int sec^2(\theta)tan^2(\theta) d(\theta)$ thanks a lot, if you want you can email me the work and answers to alternet87@hotmail.com Last edited by Sillysidley; 09-04-2007 at 04:06 PM..
