It is available from free online right here at this link. In fact Stephen Wolfram has an excellent guide to starting to use the language. Good luck on your homework! Try to watch some Mathematica/Wolfram Language instructional videos. Read about WL syntax, square brackets are only for calls to/defining functions, not for ordering expressions, use regular parens for that (). Google and other resources are your friend. When a message is issued, read it carefully and try to figure out what it means. The fact that FromAbove was blue means that it doesn't have a value. The coloring of things in a notebook can give you hints about what is going on. However, as my variables are complex, I have to solve this equation numerically and after that plot my graphs. If y and x were real numbers, it would be possible to use ContourPlot. (* this just works with the modifications to h *) After solving this equation I need to plot two graphs: the dependense of y from Im(x) and y from Re(x). Then with the above modifications, the Plot call evaluates properly. (* the values of the Direction option are + or - 1, you can play around with the below *) If you read the error message and look at the documentation for the Limit function you will see that FromAbove is not a supported value, nor is it something that Mathematica even knows about. Now you can look at why Direction wasn't working properly for you. Not to do your homework for you, I have made an edit to your first problem to make it work (changed the numbers so you have to implement it yourself, but it should give an idea).
