All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...
A gauge function $V$ for the differential equation (S) $x' = f(x, t)$ is a scalar-valued function sufficiently smooth for $dV(\phi (t), t)/dt$ to exist almost ...
