It's been half an hour that I am looking to the example 5 and I can't figured how you can state that x run from 1 to 3 and y from 1 to 2 just by looking at LL.  If I undestand this, I will know how to write those twelve points.

Does anyone would have the patience to explain it to me?

Thanks in advance.

Hi everybody

Hi,,

Here is what I am doing outside a proc()

Hi,

eq1:=(3+Pi)*x^2*sin(x^2)

Is there a way to select then remove the x^2 alone but not in the sin( )

                         Q := Matrix(%id = 52164504)

I right-click on the Matrix and Export As Table delimited and give it the name Data_plot.

Then I insert a spreadsheet in Maple and import Data_plot.  Everything work fine,
