Request for homework problems on the board next time

By request, I am posting here some homework problems which I would like to have students put on the board on Wednesday. To help save time, if you get to the classroom before class starts, you could put one or more of these on the board at that time, before the start of class – you don’t have to wait! (Reminder: You get extra credit quiz points for putting problems on the board, as well as for answering student questions on Piazza.)

From the course outline:

Any of the indefinite integrals which are mentioned in the problem section from Session 6 (they are not in the textbook). Here they are:

\displaystyle \int \frac{x^{2}}{\sqrt{4-x^{2}}}\textrm{d}x

 

\displaystyle \int \frac{x^{3}}{\sqrt{x^{2}+9}}\textrm{d}x

 

\displaystyle \int \frac{\sqrt{x^{2}=9}}{x^{4}}\textrm{d}x

 

\displaystyle \int \frac{1}{x^{2}\sqrt{4-x^{2}}}\textrm{d}x

 

\displaystyle \int \frac{1}{x^{2}\sqrt{x^{2}+9}}\textrm{d}x
