Determine the forced oscillation of a system under a force F(t) = at, if at time t = 0, the system is at rest in equilibrium (x = x' = 0)
2. Equation of motion: x" + ω²x = at
3. I've found the particular solution, but i just can't find the coeficients of the homogeneous solution (...
I need to show that: sqrt(x^2 - l^2) - l ≈ {x^2}/{2l}
2. That should be valid for x << l
3. First I've tried to isolate l in the sqrt, but it got me nowhere. Anyone could show me a simple way to solve this?
1. A p-n junction is a double layer of opposite charges separated by a small distance and has the properties of a capacitance. The resistivity of a semiconductor can be controlled by doping. Thus the elements in the trasistor circuit of Figure 13-24a can be manufactured on a p-n-p semiconductor...
