In the exercise uploaded I have to plot asymptotes of a function. I know this is possible using definitions of all kind of asymptotes and ploting in a figure. However I would like to know if exists some parameter for plot method that automatically show asymptotes.

For this question I need that who help me focus in second block of code in the document. Basically, what I am trying is to get a plot of folium of Dercastes using parametric equation to plot ordered pairs. In order to success, is needed to exclude t=-1. In the block is showed what I tried. I concluded that my approach in solving that part of exercise is wrong. What could be a well approach?

How you can see, in the following exercise I built five plots, every one with the graph of two functions. The exersise say that I must find coordinates of any intersection. I think I can do it with solve command. However, I want point out coordinates of  intersections inside the plots. Probably exists a command or a parameter to success with my objetive. How can I do it?

In document uploaded I tried to write a code to get as output 11 plots. I would like a format as this: 9 plots in 3 columns an 3 rows, and a fourth row with two center plots. To explain me better, I drew a rustic sketch of what I want, basically something like this:

However I tried but I fail and my output is horrible. So, I want to ask: Does exists some option to the plot[display] command or should I try another aproach?

This is a simple problem of Chemistry. I solved the exercise, but there are three aspects I don't like about output:
1) Even kg*m² *s^-2 = J (SI unit to energy) and both are correct, one must be explicit with units in order to be totally clear, so I need an output with units of J/mol and not kg*m² *s^-2 mol^-1.
2) I had to hardcode number of significant figures, so I had to analize quantitys in order to determine this number, wich as you can see, is three. I think Maple can compute significant figures automatically, but I could not find the command in documentation and even in this case is not totally needed, I would like to learn how do it because it could be very useful for more complex expressions.
3) Finally, output must be expressed using scientific notation, it's say enthalpy = 10.4*10⁴ J/mol.
Therefore: How can I get adecuate output?
