Exam 3 will be on Monday, November 6. It will cover 3.7, 3.8, 3.9, 6.1, 6.2, 6.3, 6.4.
Table of Laplace transforms: In the exam I will give you the following table of Laplace transforms:

tneat	n!/(s-a)n+1
eat cos(bt)	(s-a)/[(s-a)2+b2]
eat sin(bt)	b/[(s-a)2+b2]
uc(t) f(t-c)	e-cs F(s)

Note:

• With a=0 you get from the table the Laplace transforms of tⁿ, cos(bt), sin(bt).
• With n=0 and 0!=1 you get from the table the Laplace transform of e^at.
• You have to memorize the Laplace transforms of y'(t) and y''(t) for the exam!
