But then I'll draw aĬouple of type 1 regions, and then I'll showīecause sometimes that's the more important question. At first, I'll giveįormal definition makes some intuitive sense. So the first type of region,Īnd it's appropriately named, we will call a type 1 region. Useful for thinking about how to evaluate differentĭouble and triple integrals and also some interesting proofs Next few videos, I hope to explore different types I'm unsure if this is correct, but hopefully I helped. This can be considered the 3D version of the vertical line test of sorts. Likewise, for the cylinder, the green circle and purple circle are the bounds.įor the dumbbell, there cannot be a lower or upper bound that can completely bound or "wrap around" the 3D figure.Īnother thing to note is that because the bounds are surfaces, for any (x, y) (which can be imagined as a vertical line parallel to the z-axis), there can be at most 2 values of z where it crosses the boundary surfaces. Using the examples, we see that for the sphere, the upper bound is the green hemisphere, whereas the lower bound is the purple hemisphere, which are both surfaces that bound all z. f1(x, y) ≤ z ≤ f2(x, y) put into words is simply that for all z, there is a surface (because f(x, y) is a surface) f1 that is the lower bound and f2 that is the upper bound. (x, y) ϵ D simply means that x and y are part of a domain, or that the region is not infinite. We begin with the definition of a type I region (x, y, z) means that it is a collection of points in 3D space, or simply a 3D figure with volume. I'm also unsure of why that is the case, but here is hopefully a good enough explanation. The coupon codes will be the same as for Calculus 3.įeel free to share this information with your family and friends.Great question. This course will be published probably in Maj 2021, or in June 2021 the latest. Now I am recording Linear Algebra and Geometry 1. If you read Swedish, you can use my lecture notes from MDH The courses on udemy are in English, but I teach in the same way as at Uppsala University, but with more visuals because the teaching is digital. In Uppsala I got four pedagogical awards for teaching this course (and Linear Algebra and Geometry 1). ![]() ![]() I taught this course 3 times at Uppsala University (2017-2019) and 3 times at Mälardalen University (2019-2020). The second part has today 90 students from 28 countries, and the rating 4.8 out of max 5 (12 ratings and some very nice reviews). The first part has today (on April the 24th, 2021) 285 students from 43 countries, and the rating 5.0 out of max 5 (32 ratings and very nice reviews they are public and can be read on udemy). (Later, after April, the following codes will be created: TPOT_MAY21, TPOT_JUN21, TPOT_JUL21, TPOT_AUG21, etc.) The second part (44 hours) contains the rest of the course (without ODE). You get approximately 90% (the prices on udemy vary) discount if you use the following coupon Part 1 (47 hours) contains the material from the first part of the course (as in Uppsala), until the midterms, and the content is described here. ![]() The course on udemy covers both theory and plenty of solved problems (where the solutions are explained in detail, and often illustrated with pictures). ![]() The only part missing is the last module, ODE (ordinary differential equations) which usually appears in 1 (out of 8) problems during the final exam (10 hours lectures and 4 hours classes out of the total of 110). The course is now available on udemy ( Calculus 3 / Multivariable Calculus) and it corresponds to about 90% of the course in Uppsala. You get then 110 hours of teaching (70 hours lectures and 40 hours classes). During the (entire) spring semester the course is given for Engineering Physics, Electrical Engineering, Teacher Training Programme in Mathematics, the majority of them are the first-year students. Usually it is the third maths course they follow (after Linear Algebra and Geometry 1, and Calculus 1 and 2, or some variants of these courses).Īt Uppsala University, this course is given twice a year: during the (entire) fall semester for Chemical Engineering, Teacher Training Programme in Mathematics, Chemistry and IT, the majority of them are studying their second year. The course Calculus 3 (sometimes called Multivariable Calculus or Several-Variable Calculus) belongs to the hardest maths courses on many engineering programs. To everybody who studies (or is going to study) on some engineering program, and to everybody who knows somebody who does:
