I want to write a greek letter (tau) in the legend of a figure. how can I do that?
how can i move legends from bottom (default) of a figure to the side?
how can I plot a vertical line? for example x=5, starting from y=0 to y=10.
I know I can plot y=x^2 by using command like plot(x^2, x=-2..2);.
In this example we have an explicit expression of y. What if we cannot find
an explicit expression of y? For example, suppose we do not want to find
an explicit expression of y in equation x^2+y^2=1, then how can we plot this
by the way, what's the difference between forum and blog here?
i have a bunch of commands as follows, seperated by shift+return. after the last
command, a return ofcourse. Then I execute these commands by a return.
it will give a result, but next time I enter return again, it gives
another result. What's wrong?
You can test in maple. I will change
value of x. when x=400, command
tau := fsolve(S(t)=c,t, 0..infinity);
returns no solution. but start from x=500 and larger, it has solution.
The problem is, when I change x, the value of tau doesn't change
(sometimes it may change, but sometimes it wouldn't). I don't know if
it is because the assignment of S,H,F.
