#### Known errors in Course Notes

• Chap 1: The solution to 1.26 (a) should be 0,1.
• Chap 2: Defn 2.13: should be (change in y)/(change in x)
• last paragraph of p 10: "column" should be replaced by "row" in referring to Fig 1.4
• The solution in Example 2.11 and the graph in Figure 2.2 have swapped the data for Tuna 1 and Tuna 2.
• The y-intercept of the secant line in the solution to problem 2.7 should be -8.918 not -2.226.
• Definition of linear differential equation is confusing as independent variable/dependent variable are not clear in this context
• The graph in Figure 15.6 should start with a zero slope.
• The period of $tan(x)$ and $cot(x)$ is $T=\pi$. On page 274, the text seems to say that the period is $2\pi$.
