For every new portfolio, the efficient frontier as well as the point of tangency with the indifference curve is calculated (Markowitz algorithm).
The goal of this part of the study was to analyze in a systematic way the scope and the nature of first year engineering students' errors that occurred on the tasks related to point of tangency, the derivative at a point and the approximate value of a function at a point.
In this example, the match is started at 50 [Omega] and proceeds toward the point of tangency determined previously.
Therefore, the P plane must roll to and rest on a point of tangency on a steeper part of GM/|M.sub.c~ as illustrated in Fig.
This point of tangency M represents the market portfolio, i.e., a fully diversified portfolio.
When demand is concave (i.e., [p.sub.QQ] [less than] 0), raising p lowers the absolute value of the slope of the demand curve, implying that the point of tangency occurs at a larger output level for each firm (a flatter point on AC).

Equation (A2) defines the point of tangency between the indifference curve and the mean-variance frontier.
This implies that the one-shot Nash is not a feasible equilibrium of the repeated game from the union's side, while it is always an equilibrium possibility from the firm's side.(8) As [Delta] falls, the core becomes smaller and for some [Delta] = [[Delta].sup.*], the core shrinks to a point - the point of tangency between the two frontiers.
