This little two-line Maple program draws two curves y=f(x,H) on the same (x,y) plane with different values of the variable H.

f:=(x,H)->(cos(x)*exp(H*cos(x)));

plot([f(x,0.2),f(x,1)], x=0..2*Pi,scaling=constrained);

How does one get the value of H written halfway along its own curve at the point

[Pi,f(Pi,H)] ? I am using Maple 2017 (X86 64 LINUX).

f:=(x,H)->(cos(x)*exp(H*cos(x)));

plot([f(x,0.2),f(x,1)], x=0..2*Pi,scaling=constrained);

In article <e31728b2-1081-4f79...@googlegroups.com>,

Give a name to that plot, as in:

restart;

with(plots):

f:=(x,H)->(cos(x)*exp(H*cos(x)));

p := plot([f(x,0.2),f(x,1)], x=0..2*Pi,scaling=constrained);

Then add text:

display([p,

textplot([Pi,f(Pi,0.2), typeset(H = 0.2)], align=below),

textplot([Pi,f(Pi,1.0), typeset(H = 1.0)], align=above)]);

The result is not great because the added text overlaps with

the axis labels, making a mess. It's better to add the text

at the far right, as in

display([p,

textplot([2*Pi,f(2*Pi,0.2), typeset(H = 0.2)], align=right),

textplot([2*Pi,f(2*Pi,1.0), typeset(H = 1.0)], align=right)]);
