# Limits in SageMath

What is the correct coding to find limits in SageMath?

I need to determine the limit of y(x) as x tends to +infinity.

y(x) = (x - d)/(1 +(x*d))

First, note that such a limit can be computed by hand and does not requires any computer.

If your goal is to get this computation done with Sage, you can have a look at the following documentation to see how to define symbolic variables (the parameter d in your case), how to define a symbolic function (yin your case) and how to compute the limit: https://doc.sagemath.org/html/en/refe...

You can also look at the following introduction: https://doc.sagemath.org/html/en/prep...

If you want some more help, you should ask more precise questions related to your research in solving this exercise, especially where you are locked.
