Geared toward readers unfamiliar with complex numbers, this text explains how to solve the kinds of problems that frequently arise in the applied sciences, especially electrical studies. To assure an easy and complete understanding, it develops topics from the beginning, with emphasis on constructions related to algebraic operations.The three-part treatment begins with geometric representations of complex numbers and proceeds to an in-depth survey of elements of analytic geometry. Readers are assured of a variety of perspectives, which include references to algebra, to the classical notions of analytic geometry, to modern plane geometry, and to results furnished by kinematics. The third chapter, on circular transformations, revives in a slightly modified form the essentials of the projective geometry of real binary forms. Numerous exercises appear throughout the text.

The perfect sunscreen face-mist
Light, non-greasy sunscreen spray to help keep your face protected throughout an active day in the sun.

My favorite!
Best face sunscreen I've ever tried and I've tried a ton.
I have very sensitive skin and I've left this sunscreen on overnight and it has not caused any issues no breakouts.
I wish it had no fragrance but it doesn't smell the worst and my skin doesn't seem to mind.
My husband refuses to wear traditional sunscreen but he loves this one because of how light it feels on your face.

Lightweight, fast application
My go-to face sunscreen now. My favorite for rushed mornings when I don’t have much time. Tried a bunch of options including dove men care, Tula, juice beauty, cerave, laroche posay, and lumin. This and Jaxon Lane Rain or Shine are my favorites. Neither makes your skin feel dry or coated in stuff. This one smells like cinnamon to me. Slight eye burn as the alcohol evaporates, but doesn’t get into my eyes or burn during the day. Pretty good discount on Amazon sometimes!

Lightweight but questionable coverage
I traditionally used the Coola face lotion but had switched to the spray for my body so I figured I’d try the face spray. It doesn’t smell as bad as a lot of the reviews say it does. It also doesn’t really smell “tropical” for that matter, but it isn’t unpleasant. It sprays evenly and doesn’t feel heavy or greasy. My only complaint is I still got a little burnt. Full disclosure: I’m super fair and have to reapply every 30-60 minutes, even without getting wet. So maybe it’s not meant for people with as pale a complexion as me. Or I have to constantly reapply, or put the lotion underneath. But otherwise I really liked it and really like Coola products.

Must have for a hot summer!
My mom saw my aunt using it and was impressed, so she bought it for herself and my sister-in-law. They both love how gentle it feels on the skin and that it’s organic and effective.
