Guys i need some advice, for the Spring semester i have to take 2 math courses but there is one that i am not sure if i should take it. that course is Partial Differential Equations, this is the description for MAP 4401 : A second course in differential equations. Topics may includeeat Equation, Wave Equation,The Method of Separation of variables. Bessel functions and other special functions arising from classical differential equations, Sturm-Liouville problems, partial differential equations,Fourier series, transform techniques. Prerequisites: MAP 2302 (Differential Equations ) and MAC 2313 ( Calculus 3) I have met all the prerequisites but i dont know why is this a senior course, it makes me think that this class must be difficult, i dont have to take it now but i think i have to because this class is only offered in the spring, i will be graduating in Spring 2010 and if for some reason i dont pass that class in spring 2010 then i will have to wait until spring 2011. THe professor for this class told me that diff. equations and calc 3 are the prerequisites for this class but a knowledge of Advanced calculus would help. i didnt take Advanced calculus , i took and introduction to proofs which include the first 2 chapters of advanced calculus ( sequences and limits) . do you think this will be enough to be able to understand MAP 4401 ? i would like to email you the notes of this course ( there is no book for this class , just online notes at his website ) so you can tell me if the material is ok or too hard based on the prerequisites. Please include your email , or send me an email at firstname.lastname@example.org with MAP 4401 in the subject and i will email it to you , its not a big file , just 3 Mb.
