A subject you've enjoyed studying this semester

Well, in this semester there are no classes that are my preference, but if it is to study with pleasure, it should be differential and integral calculus, since it is a class that reprobates last semester, the study is quite fluid and I try to give it The greatest effort, to pass and advance in my classes. In these cases, sometimes studying tends to have difficulties, since sometimes the studies of other classes are combined, making it stressful to study differential and integral calculus. As a method of prevention what I do, is to allocate part of my time in the week to calculate and thus I can save that limit of study with other classes, although sometimes the fatigue is too much and the work is affected, these setbacks delay the study And make it stressful. In general, studying at the last moment is what he plays against, but sometimes there is no time.
In this class the main thing is to learn to integrate a function already derived, in order to find its primitive function, in this aspect we are taught a series of methods, such as the method of partial fractions, integration by substitution and integration by parts
