Hello.  I didn't try to evaluate what you posted, but at first glance, what is (e)^(...  Are you using the 2D input, or 1D.  If you are using 1D, then you need to use exp() instead of e^ for the exponential function.

If that is not the heart of the problem, then can you upload your worksheet, so we can execute it as is without cutting and pasting the above code?

Look at the Tools menu, and select Tutors, Calculus-Single Variable, Curve Analysis

You can enter your function there, and click on different options, like Max, Min, Zeros..., by clicking on the buttons.

You can also use Roots from the Student[Calculus1] package. It uses fsolve under the hood.

restart:with(Student[Calculus1]):

Roots(tan(sqrt(lambda)) = sqrt(lambda), 0..1000 , numeric );

Here is another way, similar to the above, without the use of single quotes.  It is a little bit faster for larger ranges of 'x'.

Download int_plot.mw

Look at help page for ?Digits to control how many Digits get used during the computation.  This will also affect the number of digits that get displayed.

for i from 1 to 5 do
    A:= i:
    B:= 2*i:
    C:= A+B;
    print(C);
end do:

                               3
                               6
                               9
                               12
                               15

The code modification above does what you are looking for.

Look at the help file for the ?coeffs command.

restart:

eq:=23*x^4 + (12*h)*x^2;

coeffs(eq,x);

There is another command as well.  See help pages here.

The issue with the Integration Tutor, or any other tutor for that matter, has to do with how you enter your functions.  In your specific case, you have to include the multiplication sign after the 5.  See image below.

Hello tantan.  This is a place to get help with Maple related questions.  You will have better chances with help to your question here.

The Maple equivalent of the Matlab .* command is *~.  See here for more details.

You can combine plots with the ?display function.  See below.  If this is not what you are looking for, let us know.

I am not too familiar with the Calculator, but this works;

cos(X)-X

Then click graph, and you will see the plot. In Maple, you can do it as follows.  There are other ways as well.

Here is one way:

restart:printlevel:=0:

for alpha from .4 by .1 to 5 do
S := solve(x^4-alpha, x);
print(S[2]):
end do:

It might have to do with how you entered your data.

Here is one way to do this, using the Roots function.

restart:with(Student[Calculus1]):

eq:=sin((Pi*x^2)/2);

plot(eq,x=-5..5);

Roots(eq, -5 .. 5);

evalf(%);
