Here is the homework assignment to prepare for Exam #4. The homework will be due the day of the exam (this coming Wednesday, May 17), and covers the topics that will be on the exam.

For this homework, write out the solutions to the following exercises from the Final Exam Review sheet (http://www.citytech.cuny.edu/mathematics/docs/review/MAT1275FinalRview.pdf):

#6(a) – solving a system of 3 linear equations in 3 variables (follow the steps outlined on Quiz #6)
#7(a)(b) – solving a system of 2 nonlinear equations (follow the steps outlined on Quiz #7)
#8(b)(c)(d) – applying the Law of Sines or Law of Cosines
#10(a)(b)(c) – proving trig identities

Also do the “Logarithmic Functions” WebWork set–this topic will also be on the exam. (Look can also look at #12 on the Final Exam Review Sheet.)

Notes:

For #8 and #10 above, use the “Trigonometric Identities and Laws” handout that we used in class (also available under “Files”).

For #8, first figure out whether you can use the Law of Sines or Law of Cosines, based on what information about the triangle is given, and what you are trying to calculate.

For #10, you can use the solutions to get started, but make sure you understand what is being done at each step of the solution.
