Hi, maybe you could set algsubs(x=-x,term);

and then apply asympt.

fsolve(58.54*x^2+19620*x^(1.85)-11485.54=0);

And no, it cannot be solved symbolically.

You left out the spaces after 8 and 2.5

Even better, always use multiplication signs.

plots[polarplot]([8*cos(3*θ),4-2.5*cos(θ)]);

There seems to be an already completed human hand model here:

Best would be to contact Maplesoft and ask if you can have it.

type 

solve(2*x+3*y=4,x);

and press enter. see ?solve for details.

Evaluating something inline with the = sign is a different story, it depends on your region settings which keystrokes will do that. My German keyboard layout requires pressing ctrl+alt+=  to evaluate. Anyway this way of solving stuff is not used often, because it will do only basic calculations. Use commands instead, to do specific tasks.

you cannot convert it mathematically, they are not equivalent.

0.342*Dirac(t) is not a function in the ususal sense. It has no finite magnitude.  You can only use it in an antiderivative:

try cntrl+alt+=

seq(series((1/epsilon-log(i)),epsilon=0),i={3^2,3^3,3^4});

kernelopts(version);
Maple 16.02, IBM INTEL NT, Nov 18 2012, Build ID 788210

Yes, it should work.

L:=[seq(Matrix(2,2,[[1,i],[i,i^2]]),i=1..4)];

This has to be done numerically, so use fsolve. To get a good initial starting point for the numerical solver, make a plot.

restart:
f:=sum(1/n, n = 1 .. N);
plot([f,20.12],N=1..1e9,y=20..21,gridlines=true);
fsolve(sum(1/n, n = 1 .. N) = 20.12, N=3*10^8);

Rewriting the sequence works. Time to adjust the computer lab cornerstones to be more Maple friendly :D

a := n -> cos(n*Pi)*arctan(n):
Limit( a(n), n=infinity ):
% = value( % );

Task probably is to find a radical expression.  For the conversion below, I replaced the float 7.50 by a rational, so that Maple does not use numeric. Also note that Maple expects radians as input, so I converted your degrees.

convert(sin(54*Pi/180)+cot(15/2*Pi/180),radical);

Are you interested in a graphical representation of the intersection? Then use intersectplot. Joe, shouldn't have the intersection have components in x,y and z ? It should be a 3D space curve, in general.

use combine to convert trig powers to multiple angle trigs

int(sin(x)^4,x);combine(%);
