all goes well. reviews the installer on your machine.




solve(x-8*(1/12) = 0, x)



solve({x-8*y = 0, 2*x-4*y = 1}, [x, y])

[[x = 2/3, y = 1/12]]


eq1 := x-8*(1/12) = 0;

x-2/3 = 0


solve(eq1, x);



eq2 := x-8*y = 0;

x-8*y = 0


eq3 := 2*x-4*y = 1;

2*x-4*y = 1


solve({eq2, eq3}, [x, y]);

[[x = 2/3, y = 1/12]]

@Markiyan Hirnyk 

I think ... your opinion is irrelevant and superficial.


is only an introduction to get started ...

it was time. Observed promising.

Aqui te dejo el link para que descargues los libros necesarios para tu autoaprendizaje.

adding the code for better understanding.

@Markiyan Hirnyk 

This should be as you mention but I avoid more code with decimal inches and avoid the command "distance" ie distance (o3, o4) = sqrt (20) and distance (o5, o6) = sqrt (68). But anyway thanks for the observation.

Me da gusto saber que en la comunidad se domine el español; aunque sea en forma minoritaria.


Get used to Maple 17 I teach to classrooms of 30 students on average, and I'm doing well my students are very motivated. I recommend you read books of Maple and then see the results in the management of Maple in the classroom.


Do not worry so much about the language, work the math which is a universal language, I work with maple since 1990 read books in Russian, German and French, and in this way contribute to society. Do not you think?. I want to improve my work with components.

=1/6 (sqrt((x^2+x+1)/((x+1)^2)) sqrt(2) (sqrt(3) arctanh(1/2 sqrt((x^2+x+1)/((x+1)^2)) sqrt(2) sqrt(3))+3 arctan((sqrt(2) (x-1))/(sqrt((x^2+x+1)/((x+1)^2)) (x+1)))) (x+1))/(sqrt(x^2+x+1))

solution to integral

I used here only an estimate to maple pripori with 17: you can try with limits.


Int(1/((x^2-x+1)*sqrt(x^2+x+1)), x) = simplify(int(1/((x^2-x+1)*sqrt(x^2+x+1)), x))

Int(1/((x^2-x+1)*sqrt(x^2+x+1)), x) = simplify(int(1/((x^2-x+1)*sqrt(x^2+x+1)), x))

Sorry for not having commented em English.
