Assignments and Announcements for Math 124K



September 24: Problems 1-8 and 11,12 on your first Webassign homework are precalculus or parametric equation problems, and you should be able to do them in the coming days. (Your worksheet tomorrow will deal with circles and tangent lines to circles, and I will say a few words about parametric equations on Wednesday). On Wednesday, I will also begin in on 2.1.

September 26: I discussed parametric equations and part of Section 2.1 today. You can now do Problems 13-15 from Webassign HW1. (The meaning of Problem 13 may be more clear after Friday's lecture, however.) On Friday, I will finish 2.1 and cover 2.2.

September 28: We covered Section 2.2 today, and you now should be able to do the rest of the problems on Webassign HW1. On Monday, I will cover Section 2.3.

October 1: We covered just about all of Section 2.3 today, and you should now be able to do Problems 1-8,11, and 23-25 on Webassign HW2. (These will be available at 2:00 AM Tuesday morning.) On Wednesday, we will move on to Section 2.5. (Section 2.4 will not be covered in this class.)

October 3: We covered most of Section 2.5 today, and you should now be able to do Problems 9,10, and 12-20 on Webassign HW2. On Wednesday, we will finish 2.5 and move on to Section 2.6.

October 5: We finished Sections 2.5 and 2.6 today; you should now be able to do the remaining problems on Webassign HW2. On Monday, we will move on to Section 2.7.

October 8: We covered Section 2.7 today and will cover Section 2.8 on Wednesday. Webassign HW3 should be available tonight at 10:00 PM; you will now be able to do Problems 1-10,14, and 15 from that assignment. On these problems, you should compute the derivative directly from the limit definition, even if you have learned rules for differentiation from a previous calculus course. Note also that Problem 13 has been assigned 0 points. I have included it in case you feel you need more practice on these sorts of problems.

October 10: We covered most of Section 2.8 today. You should now be able to do Problems 11,12,13, and 16-23. Once again, Problem 13 is optional and worth 0 points, and you should compute the derivatives on these problems directly from the definition. We will finish 2.8 on Friday and then move on to Section 3.1.

October 12: We finished Sections 2.8 and 3.1 today; you should now be able to do the rest of the problems on Webassign HW3. On Monday, we will cover Section 3.2.

October 15: We covered Section 3.2 today and will discuss Section 3.3 together with sinusoidal functions on Wednesday. Webassign HW4 should be available this evening at 8:00, and you should now be able to do Problems 1-21 on that assignment.

October 17: We covered Section 3.3 today and have almost finished with sinusoidal functions. You should now be able to do Problems 22-30 on Webassign HW4. On Friday, we will finish sinusoidal functions and begin in on Section 3.4, the chain rule.

Midterm 1 is on Tuesday, October, 23. It will cover all of the material up to and including Section 3.3 and sinusoidal functions. You will be allowed to bring one handwritten two-sided 8.5 x 11 inch page of notes and a scientific, but not graphing, calculator. In addition, you will need a straight edge---the edge of your page of notes should work---to draw in and measure the slopes of tangent lines.

October 19: We finished up with sinusoidal functions and began Section 3.4. On Monday, we will review for the midterm.

October 24: We finished our discussion of the chain rule; you should now be able to do all of the problems on Webassign HW4. For those who wish to start in on Webassign HW5, you should also be able to now do Problems 1-3,5,7-15,25, and 28. Keep in mind that I have made some parts of #28 worth 0 points. Also, in #25, speed is the absolute value of the velocity. On Friday, we will discuss tangent lines to curves defined by parametric equations. This material is covered in the first 3 pages of Section 10.2 of Stewart.

October 26: We discussed tangent lines to curves defined by parametric equations, and you should now be able to do the rest of the problems on Webassign HW5. On Monday, we will introduce the technique of implicit differentiation (Section 3.5 in Stewart).

October 29: We began in on implicit differentiation and will continue with that on Wednesday. Then we will discuss the derivatives of logarithmic functions.

October 31: We finished up with implicit differentiation and started in on Section 3.6. You should now be able to do Problems 1-17,24-6,29, and 37-9 on Webassign HW6. We will discuss logarithmic differentiation on Friday and then move on to related rates problems (Section 3.9).

November 2: We finished Section 3.6 and began discussing related rates problems. You should now be able to do Problems 27 and 28 on Webassign HW6. On Monday, we will do some more related rates problems.

November 5: We continued with related rates today. You should now be able to do the rest of the problems on Webassign HW6. On Wednesday, we will finish up related rates and move on to Section 3.10.

November 7: We finished up with related rates and began discussing the tangent line, or linear, approximation. We will finish that on Friday and begin in on Section 4.1.

November 9: We finished our discussion of the tangent line approximation and began Section 4.1. You should now be able to do Problems 1-9 on Webassign HW7. On Wednesday, we will finish 4.1 and move on to Section 4.3. (Section 4.2 will not be covered in this course.)

November 14: We finished Section 4.1 and began in on Section 4.3. You should now be able to do Problems 7-22,28, and 34 on Webassign HW7. On Friday, we will finish Section 4.3 and perhaps begin 4.4.

November 16: We finished Section 4.3 today; you should now be able to do the remaining problems on Webassign HW7. Monday will be review for Midterm 2 on Tuesday.

November 26: We discussed L'Hospital's Rule today; you should now be able to do all the problems on Webassign HW8. On Wednesday, we will take one last look at graphing functions using information about their derivatives (Section 4.5) and then move on to optimization problems (Section 4.7).

November 28: We finished up with graphing functions today and will begin in on optimization problems on Friday. You are already able to do Problems 1-7, and 22 on Webassign HW9.

November 30: We discussed optimization problems today and will do a harder example on Monday. You should now be able to at least attempt all of the Webassign HW9 problems.

December 3: We finished with optimization problems today and began our review for the final. We will continue to review on Wednesday and Friday.


The Final Exam is on Saturday, December 8 from 1:30-4:20. If you are in KA or KB, your room is PAA A110; if you are in KC or KD, your room is PAA A114. (PAA stands for Physics Astronomy Auditorium.)
