Answer:
Solution: In this case, the system can be modeled as a function with two output signals,

where

where(x(t), y(t)) is the position of the tail in they plane. This model Is Clearly not linear. If the Input torque doubles, for example, the output values will not double. In fact, the output values are constrained to lie on a circle centered at the origin, regardless of the Input. For this reason, the model is BIBO stable. The output is always bounded. Thus, while our previous model was linear and unstable, this one Is nonlinear and stable. Which model is more useful?
Answer:
Update the unit firmware.
Explanation:
Updating unit firmware means update the information related to the network that is newly installed on the wireless router. The purpose of this change is to update the devices with new network alterations to work with efficiency and better security. As things are updating on daily basis, so the manufacturer makes the devices, reprogram able to meet the requirement of the future by updating the program in firmware unit. By updating device means this will be to fix the bugs that can be occur in modern era. This will make the device more secure.
