- Derivative of the Volume of a Cone - Physics Forums
You will have, now, a related rate for the volume of a cone This is correct to the best of my knowledge, and I note the fact that I took the derivative of the radius, r, because it, too, is not constant (as you can obviously imagine, as it changes depending on how high or low you go in the cone) Had this been a cylinder, you would not treat r as a variable, but rather as a constant, like (π
- How is the Aging of Electronic Equipment determined?
Agreed, there is a huge difference between financial and technical lifetime The former is usually set by rules related to taxation, asset management etc and will usually be the same for all equipment irrespective of how quickly it actually ages Good quality "expensive" electronic equipment will usually last quite a while as long as it is maintained (clean out dust, replace any worn out
- Understanding dv dt: A Beginners Guide to Calculus Concepts
Calculus deals a lot with relationships of change In the case of dv dt v is one variable and t is another Typically t is the independent variable and v is the dependent variable You may be familiar with ratios of change in quantities For example if I wanted to find my average velocity (change in distance over change in time) I would take the distance I traveled and divide it by the time
- How is dθ dt related to v r in circular motion? - Physics Forums
Homework Statement just a conceptual thing I don't quite understand how come dtheta dt = v r? I thought it was basically the same thing as v = r t, but with radians thanks Homework Equations The Attempt at a Solution
- Tile Arrays Accelerate the Evolution to Next-Generation Radar
MACOM Editor’s Note: This month’s theme of radar and antennas features two articles discussing architectural changes that are accelerating the evolution to the next-generation of phased array radar The first, by Doug Carlson of MACOM, discusses the development of a tile array built with commercial manufacturing processes This approach yields a system that can perform multiple radar
