willard 0 #6 January 11, 2007 First order for now. Thanks for the offer for help. I have a couple "math geek" friends, who do these for fun, that are on 24/7 call. Last required math course!

Of course it didn't hurt that the instructor for the Diff Eq 1 was a smoking hot little blonde. My instructor for Diff Eq 2 was a ringer for Abe Vigoda.

Quote Share this post Link to post Share on other sites dbattman 0 #13 January 11, 2007 The problem I've always had with higher order math is that nothing related to anything in the real world. Here's an equation- solve it. To me it was a bunch of triangles and letters and squiggly lines. Well, you solve it and it tells you the triangle D over the triangle y is equal to arctan of the greek d times the elongated e raised to y times s. OK- big friggin deal. Glad I'm paying 350 a credit hour for this. The only thing I really understood out of diff eq was the spring/dashpot situation. you displace the spring and depending on the degree of damping you can extrapolate several equation to describe the position of the spring at any time. Neat stuff- so what. Turns out when I started to study process control the spring problem is a perfect representation of what happens to a process control loop when you feed it an upset or change the tank level setpoint from 70% to 85% That's the key- finding something tangible you can grab onto and visualize.

Math is not my strongest subject, but I've managed to claw my way this far so I know I'll find a way to get thru this course also. Some of your replies echo what my profs tell me. Out of all the math requirements for my major, this is the one class I will use the most. Trying to do math problems while engaged in heavy drinking doesn't work. You almost always get the wrong solution and it leaves you with a hangover. Hey! That's the way to avoid hangovers! Don't do math!
