摘要: Argues that the derivation of the area of a circle using integral calculus is invalid. Describes the derivation of the area of a circle when the formula is not known by inscribing and circumscribing the circle with regular polygons whose areas converge to the same number. (MDH)...
Table 2. Derivation of the moments of area using the equations for the B-spline. The comparison with the table shows an agreement of the calculation methods with the literature. Thus, it can be seen that if the control points (polygon) are repeated twice, the results from the literature ...
The error is mainly caused by the system equivalence and linearization in the derivation of the equation, but the results can meet the engineering requirements. 4.2. Influence of a DC Power Loss on the Peak Value of the Oscillations of the AC Tie-Line The DC power transmission power is ...
