### Final exam and gradebook updaes

Here you will find a google drive share of the gradebook posted in the 4.28.2016 blog post. Both have been updated. The final for MATH235B(MWF@11am) is scheduled for Monday at 10:15am in our normal classroom,…### Quiz 3 Matrix

I’ve created a quiz 3 matrix that shows which problems were done correctly, indicated by the number one, which were done incorrectly, indicated by an x, and those that where pretty okay, indicated by a…### Group work – Systems of ODE

Here you will find the submission zone for the final group work about systems of ODE. I’ll be half asleep on the floor of a high school gym and thinking of you and wondering if…### Final exam and gradebook updaes

Here you will find a google drive share of the gradebook posted in the 4.28.2016 blog post. Both have been updated. The final for MATH235B(MWF@11am) is scheduled for Monday at 10:15am in our normal classroom, BB269. The final for MATH235A(MWF@10am) is scheduled for Thursday at 8:00am, again in our same classroom. I will be testing…

### Quiz 3 Matrix

I’ve created a quiz 3 matrix that shows which problems were done correctly, indicated by the number one, which were done incorrectly, indicated by an x, and those that where pretty okay, indicated by a -. (pdf with bad formatting, excel file if you are on your computer and link to google drive element). The…

### Group work – Systems of ODE

Here you will find the submission zone for the final group work about systems of ODE. I’ll be half asleep on the floor of a high school gym and thinking of you and wondering if anyone else could begin.

### Group work – Part II

Here you will find the jotform submission for the Laplace transform work. Every great dream begins with a dreamer. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world.

### Journal Activity: Chaos, attracting sets and fractals

The dated and canonical introduction to ordinary differential equations focuses on solution techniques. Here you will find a classic exposition on the matter which was given at an invented address to the American Mathematical Society in 1997. The modern perspective is to stress concepts, see section 10 of this address, which underpin the theoretical study…

### Journal Activity: Nonlinear Autonomous Systems

We started the course with building from the simplest scalar models, which we used to model population growth and free-fall. From here, it was easy to see that introducing nonlinearity added richness to the models predictions. For example, linear autonomous population growth, , predicts a population that growths without bound but nonlinear autonomous logistics growth,…

### Final group work

Here you will find my final group project. Don’t let the size intimidate you. Groups will only be required to complete those sections labeled “required” in red. Specifically, parts of section 3 and all of section 4 and 5. Anything else completed will be considered extra and gold stars will abound. Here you will find…

### Journal Activity: Systems of Linear ODE – Summary

To move from the mass-spring equations to linear systems of ODE we noticed that it is possible to define a velocity variable so that the second order linear mass-spring equation can be treated as a system of first order equations on the displacement and velocity variables. While the point of introducing Laplace transforms was to…

### Gradebook

So, I’m still waiting on quiz data but I do have a spreadsheet full of your non-stress test data. The excel file can be found here and the pdf here. I will be in my office this afternoon getting as much data as possible entered. Feel free to stop by and chat me up if…

### 50 problems

It’s not 99 problems, maybe one day it will be, but 50 will be good enough for today. The following video playlist contains solutions to most of them. The playlist will be updated as more videos come in. I got two choices y’all, pull over the car or, hmm, bounce on the devil, put the…
