plot - Maple graphing inaccuracy -


i not used using maple, question may basic. however, cannot find helpful on internet.

i using maple 13. need draw graph or find solution of following function:

    f(x)=arccos(cos((1/273)*(2*pi*10)*t)*cos(2*pi*t*(1/365))+cos(6*pi*(1/180))*sin((1/273)*(2*pi*t*10))*sin(2*pi*t*(1/365)))

and using "plot" method in maple, tried draw graph, , can see, function periodic, expected graph so. however, graph not periodic @ all.

also, using "fsolve" method, tried find root of equations, find out disappointing result: "0.", trivial solution of all.

i figured out reason error might in function itself, or maybe it's floating point representation, since no computer code can handle irrational number exactly.

is there way handle numbers and/or sin, cos, arccos functions more accurate make outcome better?

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
