Hello,
I am using maple to plot an expression using the following file. The
strange thing is, some of the plotted value don't comply with the
evaluated value.
In the bottom of the file, I have purposely evaluated expression value at
some particular points, you can see the discreprency directly.
Could some one help me figure out why this is happening?
--------------------------------------------------------------
g := Pi*((2*R-x)^2-R^2);
Fx := exp(-m*g*(1-exp(-n*2)));
fx := diff(Fx,x);
Ex := int(x*fx,x=0..R);
tmpEx := subs(m=1/Pi,n=0.2,Ex);
plot(tmpEx,R=0..40);
v_5_tmp:= eval(tmpEx,R=5);
v_5 := evalf(v_5_tmp,9);
v_20 := eval(tmpEx,R=20);
v_30 := eval(tmpEx,R=30);
v_40 := eval(tmpEx,R=40);
------------------------------------------------------------
Thanks,
Xiaoyan
