V2 June 2014. To say that the subject of VTE prophylaxis in orthopaedic surgery is a thorny issue may be understating the case. Debate and difference of opinion is something which is part and parcel of orthopaedic surgery and one of the many. components that makes this specialty fascinating.
Note that just monotonic transformation of a concave function isnot necessarily concave: consider, for example f (x) = x and g (z) = z 3 .Thus the concavity of a function is not ordinal, it is cardinal property.Economic ExampleSuppose production function f (x) is concave and the cost function c (x) is convex.ote that just monotonic transformation of a concave function isnot necessarily concave: consider, for example f (x) = x and g (z) = z 3 .Thus the concavity of a function is not ordinal, it is cardinal property.Economic ExampleSuppose production function f (x) is concave and the cost function c (x) is convex.
If the functions fi are linearly dependent, then so are the columns of the Wronskian as differentiation is a linear operation, so the Wronskian vanishes. Thus, the Wronskian can be used to show that a set of differentiable functions is linearly independent on an interval by showing that it does not vanish identically.
