Hello Doug.

Thank you to have answered my question within such a short time.

Here my real function which is defined by f (x). Then, my preceding question was: Why I cannot calculate the limit of this function when variable X tends towards zero. Since the value of X does not exist in this function. On the other hand, when I calculate the value of f (0). The answer can be calculated. Consequently occasion. Does that give zero like answer? Would it be possible to have explanations? Thank you.

Hello Sebastian.

Would that be possible to explain me the stages in detail of the process to put your image of Worksheet? That would be really appreciated since I try to put questions which I make in Maple 12. Without success.

Thank you.
 

I would like to thank you for the assistance that you bring to me with the software. I begin and it is not always easy.

Sebastian.

By using the rules of derivation, to determine the functions derived from the following functions and simplify.

>f:=x->sqrt(x+1)/x-3;

I used the Differentiation Methods. I would like to know how to write it directly in Worksheet Mode. After several attempts, exasperated a little.

Moreover, would it be possible to indicate to me how you put your Worksheet on this forum? Thank you!

I would like to thank the people who directed me during my first work on Maple.

Would it be possible to explain me an answer obtained in Maple 12? Following the real function f (X), I must carry out calculations requested.

I must calculate f (0), which gives me 0 like answer and f (2) what gives me 2 like answer. I do not include/understand the reasoning of that. Is there an option in Maple 12 or it is possible to see calculations of those. If not, could somebody explain me with a calculation? Thank you.

Here what I did in Maple 12.

>piecewise(x<0,x^3+8,0<x<=3,x+3/x,x>3,3*x-5);

>f(0);

>f(2);

Hello,

Would it be possible to give me a model? I do not know the notations to write in Maple 12. I would like that one guides me for the stages. I do not know by where to start. Thank you for your comprehension.
