This is the introductory course in American Government, with the main focus on the national level but some attention to state and local levels as well. This OpenLab site contains course materials as well as links to news sites and a discussion board to exchange ideas. Please keep disagreements friendly, and please keep in mind that our main purpose is more to analyze than to react and fume. When the course is over, as long as you still have an OpenLab account at City Tech, you are invited to continue posting on this discussion board.

A differential equation is an equation that relates a function to one or more of its derivatives. – The above rather boring description does little to convey just how fundamental, widespread, and amazingly effective differential equations are in describing the world around us. – Examples: Anything in motion. Also, many things that are not in motion. Also, many additional things to which the word “motion” does not really apply. – Further examples: spaceships in orbit, populations growing and shrinking, a cup of coffee slowly cooling, springs bouncing, financial markets rising and falling, electrical current flowing through a circuit, ocean waves, sound waves, light waves, vibrations in musical instruments and airplane wings and suspension bridges, – More examples: Pretty much everything. Topics include methods of solving ordinary differential equations and applications to various problems.
