Differential Equations: A Visual Introduction for Beginners is written by a high school mathematics teacher who learned how to sequence and present ideas over a 30-year career of teaching grade-school mathematics. It is intended to serve as a bridge for beginning differential-equations students to study independently in preparation for a traditional differential-equations class or as supplemental material for students currently in such a class. It is highly visual with dozens of cartoon illustrations, dozens of MatLab graphs, dozens of tables, and dozens of other images throughout its 310 color pages as well as many correlative applets found on the internet that can be used to supplement the text. Comprehension and understanding of ideas is emphasized over symbol manipulation, although the latter is covered. Topics covered include definitions; Euler's method; separable, logistic, linear, exact, Bernoulli, and homogenous equations; slope fields; eigenvalues, eigenvectors, and eigenlines; solving systems of differential equations; Laplace transforms; and more.Binding Type: Paperback

Buying more!!!
I recently tried Tele Honeyball Face and Body Moisture Cream, and I’m honestly impressed. From the first use, it felt incredibly rich without being greasy, which is a hard balance to find. It absorbs quickly and leaves my skin feeling soft, smooth, and deeply hydrated all day.
What I really love is how versatile it is—I’ve been using it on both my face and body, and it performs beautifully in both areas. My skin tends to get dry, especially with changing weather, and this cream has made a noticeable difference in keeping everything moisturized and healthy-looking.
The texture is luxurious, and a little goes a long way, so it feels like a great value too. If you’re looking for a reliable, high-quality moisturizer that actually delivers on hydration, this one is definitely worth trying.

Repeat purchaser
Subtle, pleasant scent. Very creamy and moisturizing. Use on face and neck for months and have purchased multiple times. Leaves skin feeling hydrated, not greasy.

Pure, non toxic, and it really works!
I just got this and it is amazing! I am 56 and my skin that used to be oily is now like fish scales even using a shower water filter. I have been using oils and they do not help. I know now that oil just helps retain moisture but post menopause skin needs to be hydrated. One application and my skin is glowing and silky again and there is no strong scent. Amazing, pure, and fairly priced product! Will be continuing to use this. I only wish it came in an 8-12oz size but I just ordered two.

Overall really good product
Melts into your skin. My skin clears up much faster after a breakout. Smells good (in my opinion). Love the glass jar. I got it mid August and still have about a months supply left so it last awhile and I use morning and night. A little goes a long way. Skin always looks better when I wake up.
My only complaint is if I don’t let this soak in for a bit before going outside or being active it sweats out really bad.
