By: W. Michael KelleyLet's face it, most students don't take calculus because they find it intellectually stimulating.
It's not . . . at least for those who come up on the wrong side of the bell curve! There they are, minding their own business, working toward some non-science related degree, when . . . BLAM! They get next semester's course schedule in the mail, and first on the list is the mother of all loathed college courses . . . CALCULUS!
Not to fear—Idiot's Guides®: Calculus I is a curriculum-based companion book created with this audience in mind. This new edition continues the tradition of taking the sting out of calculus by adding more explanatory graphs and illustrations and doubling the number of practice problems!
By the time readers are finished, they will have a solid understanding (maybe even a newfound appreciation) for this useful form of math. And with any luck, they may even be able to make sense of their textbooks and teachers.

A Skin Saver
I've been using the Centella toner for a week now, and it's quickly become a staple in my skincare routine. Infused with Centella Asiatica extract, this toner is perfect for calming irritated or sensitive skin. The texture is light and watery absorbs quickly without any sticky residue making it ideal for layering or using as a refreshing mist throughout the day.
It is very soothing reduces redness and inflammation, especially after exfoliating or sun exposure. It is very hydrating and gives a subtle moisture boost without clogging pores.
It has no alcohol or fragrance, so it's great for sensitive or acne-prone skin.
I use it after cleansing and before serum, and I’ve noticed my skin feels more balanced and less prone to breakouts or irritation. It pairs well with other products and hasn’t caused any pilling or sensitivity.
If your skin leans sensitive, inflamed, or needs a calming reset, this Centella toner is worth trying. Affordable, gentle, and effective. I definitely recommend this product
