The amounts of radioactivity present were infinitesimal.
These examples represent an infinitesimal portion of the space created by juxtaposing variations of just one theme against each other.
In this case, the robot will be able to have an infinitesimal motion around the singular configuration while the lengths of the links are fixed.
The general infinitesimal analysis is then applied between the configurations.
The conclusion is that a flux rope placed in a sheared flow is unstable to small (but not infinitesimal) perturbations.
The approximate solutions also show that infinitesimal, critical, waves will not exist, since their energy will be infinite.
In the latter case, however, the results are valid only for infinitesimal waves.
Such a combined method would firstly use the inverse position analysis to determine the initial joint configuration, and subsequent steps would use an infinitesimal method.
As usual, the local angular momentum conservation law is obtained from infinitesimal rotational invariance.
