### MATH222

Partial differentiation, multiple integrals, and topics in differential and integral vector calculus, including Green's theorem, Stokes's theorem, and Gauss's theorem for students with a background in linear algebra. Not open to students who have taken Mathematics 202 or 212. Prerequisite: Mathematics 221. One course.

##### Information for Math Majors and Potential Math Majors

Math 222 is offered in Spring semesters.  One of Math 212 or Math 222 is a prerequisite for the mathematics major.

Prospective math majors who enter with advanced placement credit for Math 21 and Math 22 that feel confident of their previous math are encouraged to take Math 221 Linear Algebra and Applications in their first semester followed by Math 222 Advanced Multivariable Calculus in their second semester.

This sequence is also suggested for students who are interested in getting a more solid mathematical foundation for future work.  We recommend this sequence because vector calculus naturally depends on concepts and techniques of linear algebra. As a result, a vector calculus class which assumes linear algebra as a prerequisite can offer a more sophisticated treatment of the material.

##### Information for Engineering Majors, and Engineering/Math Double Majors

Engineering students should make sure their engineering major approves swapping the typical math sequence for engineers--Math 212, 216, 353--with Math 221, 222, and 356. Consult with your Director of Undergraduate Studies.

Question: As an engineering major, does getting a double major with math mean that in effect Math 216 Linear Algebra and Differential Equations is being replaced by two courses, Math 221 Linear Algebra and Applications and Math 356  Elementary Differential Equations?
Answer: Math 221 and Math 356 together cover everything in Math 216 and 353 and quite a bit more. Math majors should have the depth and thoroughness contained in Math 221 and Math 356.  Math 453 covers additional material on partial differential equations that (though not required by Pratt) would be a good math major elective as it would cover materials very relevant to engineering.  Math 551 is also a great choice.

Question: What if I take Math 221 Linear Algebra and Applications and then decide I do not want to take Math 222 Advanced Multivariable Calculus? May I still take Math 212 Multivariable Calculus?
Answer: For engineers, this is at the discretion of your Pratt dean; for the math major, taking Math 221 followed by Math 212 is fine.  Note that you cannot take Math 216 after getting credit for Math 221.

Question: What if I'm an engineering student, and after completing Math 216 Linear Algebra and Differential Equations, I decide I want to be a math major?
Answer: You'll need to meet with the Director of Undergraduate Studies in Mathematics concerning the missed material in linear algebra.

Question: As an engineering student who is considering majoring in math, suppose I take Math 221 and then decide that I do not want to get a double major with math. Am I locked into taking Math 356 Elementary Differential Equations?
