Requests for equations should go here. Start your request with an asterisk and end it with your signature, which is four tildes. For example:

* Damping ratio for a second-order system (4.39, p. 180)? ~~~~

will show up, for Dr. G, as:

• Damping ratio for a second-order system (4.39, p. 180)? DukeEgr93 02:20, 23 February 2011 (EDT)

When I respond, I will move the request to the response page and it will look like:

Update

The equation sheet for Test 1 for Spring 2011 is now available: Equation Sheet. You will be provided a copy for the test; you do not need to print your own.

Denied / Must Memorize / Not Needed

• Laplace Transform Table (Table 2.1, p. 36)? - not needed
• Op amp general gains (2.97, p. 59 and 2.103, p.60) - must memorize inverting/non-inverting paradigms and gains
• Mechanical rotation and translation impedances (Table 2.4 on p.62 and Table 2.5 on p. 70) - must memorize
• General 2nd order transfer function (4.22, p. 174) - need to memorize - note that to be truly general there needs to be a multiplicative constant Failed to parse (: Invalid response ("Math extension cannot connect to Restbase.") from server "http://wikimedia.org/api/rest_v1/":): {\displaystyle K} in front of all that.
• Mason's Rule (5.28, p. 252) - need to memorize that and what the terms mean.
