Based on his extensive experience as an educator, F. G. Tricomi wrote this practical and concise teaching text to offer a clear idea of the problems and methods of the theory of differential equations. The treatment is geared toward advanced undergraduates and graduate students and addresses only questions that can be resolved with rigor and simplicity.Starting with a consideration of the existence and uniqueness theorem, the text advances to the behavior of the characteristics of a first-order equation, boundary problems for second-order linear equations, asymptotic methods, and differential equations in the complex field. The author discusses only ordinary differential equations, excluding coverage of the methods of integration and stressing the importance of reading the properties of the integrals directly from the equations. An extensive bibliography and helpful indexes conclude the text.

Very good signal repeater
Style: 1 to 1 IR Repeater
Fantastic product! I have a center channel for my surround sound that blocks the infrared sensor on my Sony Bravia TV that never works. I always have to get up to turn the TV on or off as well as other functions. So I purchased this product and it worked like a charm. Very simple to install, took less than 5 minutes . I didn’t have no compatibility issues. It was plugged play . Simply stick on the transmitting sensor by the receiving sensor on the TV and then the extended sensor for receiving from your remote control put where you would like it, lastly plug in the USB plug into any 5V power block and you’re done. Now I have no issues with range with controlling my TV, which is great.!👏🏼. Definitely a good product. I would highly recommend…

Easy to Set up
Style: 1 to 1 IR Repeater
Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.

Works just as advertised!
Style: 1 to 1 IR Repeater
Super east to set up. Haven't had any issues in our very long living room so it must work at around 25ft

Works as advertised with minor aiming quirk
Style: 1 to 1 IR Repeater
Setup was quick and straightforward. I plugged it in, placed the receiver, and it started relaying signals right away. It does exactly what it is supposed to do and successfully extends remote control range to my equipment without any complicated configuration.
The only issue I have noticed is that it can be a little directional. I sometimes have to angle my remote slightly from the left or right instead of pointing straight at the receiver for it to register consistently. It is not a dealbreaker, just something to keep in mind when deciding where to place it.
Overall, it performs its intended function well and is a solid option if you need an IR repeater, especially considering the price and simple setup.
