You have to type after getting the answer. or use substitution in the command line itself.

(a=7)*3*4 and press (control plus =)

Hope it satisfies you. Cheers. Ramakrishnan v

I attach herewith my document . Hope this clarifies the usage so simple.

Simply right click and and select the unit you need. It gives without any waste of second!

Go to calculas pallet. Select the d^2/dxdy f and modify the functionf as u require using the pallet expression.

I shall attach an example. Hope u can view this. The error code shown is because i did not use pallet expression.

The second one is correctly evaluated since i used expression pallet to define the function f as x/y.

I hv answered first part. Solving two diff. equns. as an example. You can proceed in a similar way for any number of equations!

Pl. see uploaded worksheet.

Graph plotting is possible once a solution is obtained in an equation form. Any equation can be plotted with a simple plot command.

I ran your program in Maple18 and the error that comes is 

Error, unable to match delimiters

This error appears when there are unmatched delimiters within an expression. In Maple, the bracket delimiters (, ), [, ], {, }, <, and > work in pairs, and an error occurs if a delimiter is used and cannot be matched with its pair.

Hope in any way it helps you.

#return "foo"; 

The above statement needs to be

#return "f()";

it will work.

solve(2*y-(x-1)^2=2,y) is in text format and hence invalid input.

Ensure that all the characters are in maths format ( maths 2D format)

solve(2*y-(x-1)^2 = 2, y);
print(`output redirected...`); # input placeholder
1 2 3
- x - x + -
2 2
solve(2*y-(x-1)^2-2 = 0, y);
print(`output redirected...`); # input placeholder

for i to 9 do if A(i) = 1 then A(k) := 100 end if end do

will work

Use i inside loop also

Assign not equation

A:= 0 and not A = 0

Hope this clarifies. I am also learner and hope to learn more from mistakes from peer group as well. Cheers.

All 3 procedures given below give answer plot.

filter := proc (x) options operator, arrow; if x < 10 then 1-(1/10)*x else 0 end if end proc; plot('filter(x)', x = 0 .. 20)

filter := proc (x) options operator, arrow; if x < 10 then 1-(1/10)*x else 0 end if end proc; plot('filter(x)', 'x' = 0 .. 20)

filter := proc (x) options operator, arrow; if x < 10 then 1-(1/10)*x else 0 end if end proc

plot('filter(x)');

All the above three works. May be the plot command takes default values for x even if not given as per my third command above.
