Dear members;
I have been embarrassed about a function Plot.
I would like to plot a curve defined as follows:
f(\[Alpha]) = (\[Rho] + \[Delta] - \[Delta] \[Alpha] - Sqrt[\[Delta] \[Rho] \
\[Alpha] (1 - \[Alpha]) + \[Rho]^2 \[Alpha]])/((\[Rho] + \[Delta]) (1 \
- \[Alpha])).
Here, 0 < \[Alpha] < 1.
And I programmed in this way;
Plot[f(\[Alpha]), { \[Alpha], 0 < \[Alpha] < 1}]
The curve I obtained from Mathematica is monotonously decreasing. AS a result, f(1) =0.
However, by using l'H=F4pital7 theorem, f(1) = 1/2 is correct.
In this situation, I would like to obtain an accurate curve.
Sincerely,
Fujio Takata
Kobe University, Japan.
I use Mathematica 8.040, Macintosh version.
