Test #3

Test #3 is Thursday, April 24. Solutions. You may bring one one-sided, hand-written, 5"x8" note card with you, and a non-programmable, non-graphing, non-symbol-manipulating, scientific calculator. The test will focus on: Ch. 11: all of it. Ch. 10: sections 4,5. We will start reviewing Thursday, April 17, and all of class Tuesday 4/22 will be for review. Please work hard now to identify what might give you trouble on the test, so we can sort it out before then.

Power series example

	etc. At each x, we have a (numerical) series. Some of these series converge (in fact, all the ones with 4 &le x < 6), and the others do not. Click here.
