Assigned week 9 Block 5, for Wednesday, November 3, you should work the following implicit derivatives as practice:
x3+y3=xy, find dy/dx

Use tan(arctan(x))=x to find the derivative of arctan(x).

Find the equation of the line tangent to x2+9y2=25 at the point (4,-1).
This work does not need to be turned in.

• Explain your work and show where numbers come from
• Use 2-up when printing Maple worksheets
• Staple - the grader disclaims responsibility for pages that are lost because they were not stapled.
• Do problems in the order in which they are listed
• Number problems as they appear in the book

The homework assigned Week 8 Block 2 is Section 3.7, numbers 2-6,13,16,21,29 from the Calculus book.
Be ready to discuss the problems Tuesday in class. There is nothing that needs to be handed in from this assignment. You will be expected to be conversant with the material and be able to ask good questions (if you are unclear on the material) or provide helpful insights (if you understand the processes involved) during Tuesday's class.

The homework assigned Week 8 Block 5 is Section 3.7, numbers 33,39,44,46,48,52,53 from the Calculus book.
I expect full formal write-ups of these optimization problems. That includes justification that the answer that you found really is the MAX/min requested. The work is due by 5PM, Friday, October 29.
It may be turned in either to me or to the slot on the wall outside my office (G215-A).

Your homework assigned Week 5 Block 5 is in the file hwvec2.mws in this directory. It is also available at IFYCSEM's Week 5 Block 5 site. The work is due by 5PM, Monday, October 11.
It may be turned in either to me or to the slot on the wall outside my office (G215-A).

Your homework assigned Week 4 Block 11 is in the file hwvec1.mws in this directory. It is also available at IFYCSEM's Week 4 Block 11 site. The work is due by 5PM, Tuesday, October 5.
It may be turned in either to me or to the slot on the wall outside my office (G215-A). Your homework assigned Week 4 Block 2 is in the file svat1.mws in this directory. It is also available at IFYCSEM's Week 4 Block 2 site. The work is due by 5PM, Wednesday, September 29.
It may be turned in either to me or to the slot on the wall outside my office (G215-A).Be sure to clearly indicate that this is the Week 4 Block 2 homework

Your homework assigned Week 3 Block 11 is to memorize the nine famous derivatives and the corresponding antiderivatives, and do the following exercises: section 4.1 #42,43,44,45,47,63,74.
Turn in the exercises from Section 4.1 by 5PM, Tuesday, September 28.
It may be turned in either to me or to the slot on the wall outside my office (G215-A).Be sure to clearly indicate that this is the Week 3 Block 11 homework

The Week 3 Block 5 homework, assigned September 21, is due by 5 PM on Friday, September 24. It may be turned in either to me or to the slot on the wall outside my office (G215-A).
You should make sure to work through the product, quotient and chain rule exercises to familiarize yourself with them before Thursday's mathematics lecture.
Be sure to use the limit definition of the derivative on the first section of the homework. (famous derivatives)
The Week 2 Block 2 homework, assigned September 13, was due by 5 PM on Friday, September 17. It may be turned in either to me or to the slot on the wall outside my office (G215-A).
The assignment was moved to Friday due to the difficulties caused by Tuesday's power outage.

The homework assigned Thursday, September 9 was due by 5 PM on Monday, September 13. It may be turned in either to me or to the slot on the wall outside my office (G215-A).
You should read through the online trigonometry review.

The Maple file to be used in class on Tuesday, September 7, may be downloaded by clicking on the colored, underlined portion of this sentence, right-clicking and choosing the Save Link As... option.
Notice that this file also has times for sunset as well as normal daily high and low temperatures. Each of these may be modelled by a periodic function. What functions model average high temperature, average low temperature and sunset times?
The homework assigned Tuesday, September 7, is due by 5 PM on Thursday, September 9. It may be turned in either to me or to the slot on the wall outside my office (G215-A).
It has been pointed out to me that minimizing the distance between the boat and the pier in 8 is silly. The last sentence of 8 should read "Determine the minimum distance between the boat and the buoy."
