Problems decorated with an asterisk (*) will not appear on quizzes or exams but are interesting extensions of material we have discussed.
Problems that prompt the use of software (e.g. HPGSolver) should be completed by the appropriate resource given below (e.g. Online slope field generator).
You can find selected solutions to some exercises from the text here. You may find it more useful to use the solutions directed to from linked section numbers. These include all exercises assigned for that section. Use these to check yourself and help in your selfstudy. Remember that mathematics is only mastered by effort, not observation.
