plot sin(x)/x

Hi friends,

I would like plot the function sin(x)/x. Of course for x=0 you get in the denominator a problem, but sin(x)/x get 1 for x=0. How can we manage this problem?

Thanks for help.

I'm not able to understand the issue. When I try to calculate/plot sin(x)/x for x=0, I get an error. Could you share your code? I don't see how you get 1 for x=0.

Hi,

the problem is:

Mathematically sin(x)/x approximates to 1 if x comes more and more nearer to 0. Just have a look in Google for sin(x)/x. You will get immediately the graphic of this function.

You're right. It does go to 1. The thing is Scilab checks for certain pre defined errors before executing the code.

You could use errcatch with the action option to continue execution of your code.
