What is $\ln(1)$?

Set up the partial fractions $$\frac{1}{(x-1)^2(x^2+2x+2)^2}$$

Set up and solve the partial fractions, try using the Heaviside cover-up method. $$\frac{x}{(x-2)(x-3)}$$

What is $\int \sec(\theta) d\theta$? Note: The easiest way to do this is just to recite the formula from the book found in section 7.2.

What is $\int \frac{1}{\sqrt{1+x^2}} dx$ Note: Some students get this confused with another important integral. Don't get confused.
