Most students have encountered functions that oscillate in time; few have applied the same reasoning to functions of space. text/html 2011-07-04T14:39:58-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:prereq:ospre:ospresfharmdrive?rev=1309815598 Prerequisites Knowledge of the behavior of the free, underdamped oscillator from previous class activities. text/html 2012-05-30T19:57:37-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:prereq:ospre:ospresho?rev=1338433057 Prerequisites text/html 2011-07-04T14:39:45-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:prereq:ospre:ospretopic1?rev=1309815585 Prerequisites Basic complex arithmetic in a+i b form; i = sqrt(-1), addition, subtraction, multiplication of complex numbers, complex conjugate, manipulating complex fractions so that i is in the numerator only.
