Requiring only an elementary knowledge of ordinary differential equations, this concise text is dedicated to helping engineering students solve problems in their field involving partial differential equations. No emphasis is placed upon questions of existence, uniqueness, and convergence; the treatment's focus remains firmly on the practical solution of partial differential equations.The first chapter derives some of the more common partial differential equations associated with such phenomena as vibration, heat flow, electricity and elasticity. Subsequent chapters examine and apply the techniques of Fourier analysis to these equations, and then extend the discussion to the Fourier integral. The final chapters explore Legendre, Bessel, and Mathieu functions as well as the general structure of differential operators.
For undergraduate engineering students.

Perfect sized floating shelves
Color: Black, Size: 24 inches, Color: Black, Size: 24 inches
These are great and the perfect width. I had my contractor install them because my tile had to have a hole drilled into it. I love that it looks seemless and flat to the tile. New bathroom renovation. I am very pleased. Holds a few towels also candles and a little plant with extra space. Perfect for a minimal look or if you have a small bathroom. Color was spot on.

Not What I Expected
Color: White, Size: 32 inches
This set of floating shelves was a disappointment. They’re advertised as holding 20 pounds, but mine began to bend with barely 10 pounds on them. All the screws and anchors were installed tightly and correctly, yet the metal brackets still warped under minimal weight. The shelves look fine on the wall, but I’m leaving them up only because I don’t want to patch a dozen holes—not because they’re sturdy. Definitely not the quality or strength I expected.

Sturdy, secure, well-crafted, and gorgeous.
This is a dark photo but I ordered this for a safe and beautiful space to keep the ashes of my past pets who meant the world to me. It is true to size, holds weight exactly as described, easy to assemble, and securely mounted with everything you need included - they even send a magnetic screwdriver for you.
The variety of lights colors and modes are exceptional, and there are dimming features and many permutations of light sequences and patterns you can choose from if you want to give it an automatic setting. It's a perfect final resting place for my pets where I know they can be honored beautifully for the rest of my life. Recommend this purchase for any project on your list requiring a shelf with a lighted back. The hanging hooks and lower bar are an added bonus. High quality product, very versatile, and amazing value.
