If you'd like a more portable copy of the exercises (with answers) for the sections we cover in MATH 193 from Washington, they are available via print-on-demand through the Interurban Satellite Printshop in the CBA Atrium (hours given in the link). Just ask them to print the "MATH 193 Course Materials" for you, since they have the file on a flash drive.

### Recommended Exercises

The recommended exercises from the textbook and the statistics problems can be found on the Homework page.

### Textbook Corrections for Washington

Ninth and Tenth editions

• Section 28.2: There is an error in the answers in the back of the text to Section 28.2, #37. The correct answer should be y=ln(3.5/(3+cos x)) + 2 -- in other words, the 2 should be outside the ln brackets, not inside.
• Section 28.6, question 29: in the question, the x3 in the numerator should be x2 (squared instead of cubed) instead.
• Section 28.7: I'm told that in the digital version of the tenth edition, the answer to #9 (maybe #7?) should be 2x tan-1x - ln (1+x2) + C (the square root is incorrect)
• Section 31.4: In the 9th edition (and possibly the 10th, but I don't have that edition handy), the answer to Question #17 should be y = x + ex / 2 - 1 + C e-x (the textbook answer is missing the e-x on the term with the C)
• Section 31.10: In the Student Solution Manual (SSM), Question #9: because the right-hand-side of the DE is just a constant, your particular solution Sp should just be a constant (A, for example). You do not require a linear term in t.

Eighth edition

• There is an error in the Student Solutions Manual. The answer for Section 28.8 - #5 in the back of the book is correct, but in the solutions manual, you'll note that if x = tan θ, then dx cannot be sec θ tan θ dθ -- it must be sec2 θ dθ instead.
• There is an error in the answers in the back of the text to Section 28.2, #37. The correct answer should be y=ln(3.5/(3+cos x)) + 2 -- in other words, the 2 should be outside the ln brackets, not inside. Many course materials are available in the Adobe Acrobat PDF file format.
