I have retired as Professor-Mechanical in Sri Venkateswara College of Engineering and Technology under Anna University affiliated colleges in Tamil Nadu, India. I have 19 years of Industrial and 20 years of teaching experience. I am learning Maple for the past four and half years hoping to make at least one appreciable maple presentation.

Dear Professor, Thank you so much. It works fine.

## Solution Obtained from acer - Thanks for...

I have referred only the digits after the decimal point.

I considered that A decimal refers to any digit after the decimal separator, such as in "3.14 is the approximation of π to two decimals".

Sorry for not very clear in my usaget.

%2.3g is what normally i use. What is f stands for? I do not understand the following from help page.

The object is formatted as a fixed point number. The number of digits specified by the precision appears after the decimal point (the six digits, if no precision is specified).

Thank you very much.

Ramakrishnan V
You have considered 6 digits total with 3 after decimal pointer. [099.999 or 99.999 or 999.99 or 099.990 or 99.99 as per data].Am I correctly understood?

## @adel-00  Contour is a locus of po...

Contour is a locus of points that satisfies all the three expressions here. The expressions given here are lamda1 = numerical values, lamda2 = numerical values and third is a function of Result, lamda1 and lamda2 which should be zero since contours = 0. Since this as an equation, i changed it in to an expression for Results  in terms of lamda1 and lamda2.Then it is simple coding to plot the three expressions as contour. The commands are

Result := (lambda__1*Pi*(lambda__2+1)^2/(4*lambda__2))^.5;
with(plots);
contourplot(Result, lambda__1 = 0 .. 1, lambda__2 = 0 .. 1);

## FormattedOutput_TextArea...

Dear Professor, It worked very well. I attach the document for just reference. Thanks. Ramakrishnan V

I have done it using the print format directly with variable values. This is fine for me.

 Maple:        Maple:     Map   9.9876:   9.0808       8.1

I have done it differently defining a variable for the print format. This is fine for me and required as standard.

Hope it is not too late:

I attach a checkboxembedded component examples i made which works. Please see if you can its worth for teaching/use.

Thanks for using.

## Module inside module...

Dear John Fredsted, I did not know about usage of 'module inside module' also. I understood from your answer about the term export and how to use export with module. I found an app very useful and was tying to make one similar for curve fitting in my project. I enclose herewith the same though it was from clod i got it. It involves startup code where in everything was programmed using module 'action'. Therefore I wanted to know about it. No problem if this could not be taken up further.

## thank you for module answer...

Ishall

Thank. How is it used. What is the answer ? How is the problem framed for this answer?

n(10) = 20 is the answer ok.

will m1 give the same answer.

will m2 also give the same answer 20. To be specific I want a command to plot sin(x) in a plot0 area embedded area using this.

Hope I am not more confusing. Thanks.

## Maple2017.2 Release...

Congratulations. MapleCloud improvements should invite more participants and knowledge sharing among the users.

With more translations, Maple has all the power and potential cover a wider world network.

Cheers.

Thanks.

## depracated parameters...

Could you please correct my doc wherein the codes mentioned in yr msg do not work. Thanks. Ramakrishnan V

 restart:

## Numeric solution...

Your 3 line command was very useful in my understanding the logic behind solving coupled odes.

1. Each second order differential equation (for solving),  needs just two known quantities: initial values and initial slope

2. Even coupled equations the above requirements are sufficient.

3. For n number of equations to be solved, 2 n quantities are required.  Here 3 equations and hence 6 initial conditions.

Thank you very much.

Ramakrishnan V

## Thanks...

plot command is seen in your doc. Thanks.

rhs is visibly F(t) and not the expression. This is one case where maple (behaves like a human) has rightly nterpretted the middle term as rhs and gives the required plot (y vs t and not F vs t).

Thanks.

Ramakrishnan V.

## Numeric Values - use For Loop...

use of for loop may help.

I am not getting the answer shown in your message. hence i assumed a function (in place of yr rhs of solution
