I am trying to evaluate an integral and expecting an expression as a result. But the following code does not provide expression.


I am geting


I need help.






Let say, I have two plots

P1:= plot(........):
P2:= plot(........):

We can display in one plot as



My question is, is there any way to combine these two plots into one and then display.

For example:  

P:= combine(P1, P2);



The reason for asking this question:

I am plotting multiple curves in a loop depending on some conditions but I can't display them in one plot. They are all appearing on different plots.



Hi Everyone,

I want to draw a 3D cylindrical object with follwoing constraint:

(1) For z=0 to 5, it should be a cylinder with radius 2 units

(2) For z = 10 to 20, it should be a cylinder with radius 8 units

(3) Connecting piece between z=5 to 10 is a type of cylinder such that its radius increses from 2 to 8 as z moves from 5 to 10.


I know how to draw (1) and (2) individually, but can't make a connecting object.

Can anyone help me drawing that object?

Thanks in advance.

Hi All,

I would like to create a 3D plot or surface plot and got stuck here and need your help.

I have a text file cretaed from C++ program. This file contains data in 8 columns. The first columns are X and Y values and rest of the columns are my calculated values based on X and Y. How can I visualize column numbers 3 to 8 based on X and Y values? Here is a sample:

0.00 0.00 0.378629 0.043703 0.259182 0.221199 0.181269 0.139292

Is it possible to create animation of convolution of two functions?

For example f(t)=u(t)-u(t-2) and g(t) = tu(t)-(t-4)u(t-4), where u(t) is a step function.

I would like to generate animation for this convolution.

Any help would be appreciated.
