A caution to mathematics professors: Complex Variables does not follow conventional outlines of course material. One reviewer noting its originality wrote: "A standard text is often preferred to a superior text like this] because the professor knows the order of topics and the problems, and doesn't really have to pay attention to the text. He can go to class without preparation." Not so here -- Dr. Flanigan treats this most important field of contemporary mathematics in a most unusual way. While all the material for an advanced undergraduate or first-year graduate course is covered, discussion of complex algebra is delayed for 100 pages, until harmonic functions have been analyzed from a real variable viewpoint. Students who have forgotten or never dealt with this material will find it useful for the subsequent functions. In addition, analytic functions are defined in a way which simplifies the subsequent theory. Contents include: Calculus in the Plane, Harmonic Functions in the Plane, Complex Numbers and Complex Functions, Integrals of Analytic Functions, Analytic Functions and Power Series, Singular Points and Laurent Series, The Residue Theorem and the Argument Principle, and Analytic Functions as Conformal Mappings.Those familiar with mathematics texts will note the fine illustrations throughout and large number of problems offered at the chapter ends. An answer section is provided. Students weary of plodding mathematical prose will find Professor Flanigan's style as refreshing and stimulating as his approach.

Individually wrapped blades for hygiene
Size: #14R, Style: Pack of 20
Very hygienic that it comes in individual packaging! Every blade comes with a cover and a small sandpaper to keep the blades sharp! Perfect to keep reusing on their own.

Great for Peach Fuzz, But Not as Sharp as I Expected
Size: #14R, Style: Pack of 20
I really liked that each dermaplaning blade is individually packaged, which helps keep them clean and sanitary until you’re ready to use them. As a hairstylist/barber who works with sharp tools every day, I did not feel like these blades were particularly sharp. That may actually be a positive for someone who is new to dermaplaning and wants something a little less aggressive.
I used them on dry skin, but you can also use a facial oil for more glide. They did a nice job removing peach fuzz and left my skin feeling smooth afterward. Just be sure not to use them over active acne or irritated areas.
While they worked well on facial hair, I didn’t notice much additional exfoliation from my first use. I’ll continue using them every couple of weeks and see how they perform over time. Overall, a decent option, especially for removing peach fuzz.
