Functions, Limits and Continuity PART 1

This is the first installment of my lecture series on Functions, limits and continuity. These three topics are essential on the study of DIFFERENTIAL CALCULUS.

Videos on Differential Calculus
PARTIAL DIFFERENTIATION

APPLICATIONS OF DERIVATIVES

DERIVATIVES OF TRANSCENDENTAL FUNCTIONS

DERIVATIVES OF ALGEBRAIC FUNCTIONS

FUNCTIONS, LIMITS AND CONTINUITY

This video really helped me to better understand functions. Before, I'm having a hard time understanding domain and range but through this video I was able to understand it. Thanks a lot sir!

A vast topic that could take 3hrs of discussion. Only took 45mins!!? This is the most comprehensive yet concise discussion I've watched. Every possible situation was discussed with appropriate examples and explanation (sometimes in depth). This is a good refreshment for what I've learned in Senior High School. Thank you for sharing this sir!

There are certain things about functions where I really don't understand, but when I watched this video, this enlightened me on some of the parts where I tend to get a hard time understanding it. This video explained to me clearly what must be done and what to consider when solving and graphing functions, as well as, it gave enough examples for the viewers to know more about different kinds of functions.

This video really helped me to understand function. It tackles how to get the domain and range which is a great help for me to recall what I learned during my senior high school study. Watching this video is like having a movie marathon, it's not boring and it's legit that you'll understand every word he said. Dr. Renson made it easier for students like me who's having a hard time understanding calculus.

The presentation was great and clear that you can understand it very well. The pace of his explanation was rather not fast that I can almost follow with him, which is one of the problems some may encounter in other teachers. He made the explanation of functions for slow learners to be understood more easily. This will help me in learning calculus in a slow pace and to understand it well.

Posting videos like these will not just serve as lectures for students but also as review for those who already finished the course. Despite the length of the video, I was able to keep focus as the lecturer has been active and meticulous of defining and providing us solutions needed to solve problems under functions, limits, and continuity. I also liked the way how the lecturer expounded the first part of the module as there were topics or concepts that were not included in the given module. Overall, I am beyond grateful for having this kind of teaching approach for it is inclusive especially for those who are not able to attend a synchronous class.

This video refreshed my mind into what we have learned when we were in senior high school. This also helped me to clear the unanswered questions in my mind when I was in shs. It made me understand each topic much more easier. I'm very sure that everyone would understand the topics mentioned because of this specific video. I would definitely recommend this to anyone who is struggling on these topics. Thank you so much for this video, Sir! God bless and keep safe.

[marianjanebartolome]

This video clearly explains what functions, limits and continuity are by providing set of different examples with clear explanation of the process. It helps me understand what domain and range is and how to graph the functions considering the limits.Looking forward for more helpful videos Sir. Thank you and God bless!

[ramilrosales]

The video provides sufficient and clear explanations about the topic making it more comprehensible for us, viewers. The discussion thoroughly explained the concepts of functions from its definition up to its application. The video helped me a lot in reviewing the topics and the simplified explanations made me understand the topic well. Thank you and I am looking forward for more videos! God Bless.

[marinellebanez]

This video helps me to recall the lesson about functions and be more knowledgeable about this topic. Sir discussed the topic detailed and explains it well so it help me to easily understand the topic. This discussion is a great help for many students who do online classes.

[shairamaeadia]

As a freshman student in engineering, this video help a lot for me. Especially that I'm feeling so hopeless for online class. Easy to understand and analyze functions. Thanks sir!

[miguellacastillo]

The presentation absolutely enlightens my knowledge about functions. It does not just helped me to recall the lessons I’ve learned before when I was in Senior High School but it also helped me to catch up new techniques and rules that can be applied in functions especially in graphing a function and finding its domain and range. Thank you so much, Sir! Will surely watch this again and other of your videos 😊

[angeloalmarez]

This video is really good for a slow learner like me. This material alleviate my questions about functions because the definition and samples of it are clearly stated and presented such as how to apply the vertical line test, the mapping which connects the domain and range. I recalled how to evaluate functions because of it. Meanwhile, he still highlightened even the small details which make his video recommendable. Mr. Renson is a witty presenter. However, I think that I need to watch this 45min video thrice or more in order to master the topic.

[nanrefjayflores]

Thank you sir for the presentation! By watching your presentation, you clarified everything and explained very well. I learned from you very clear. You explained the lesson very well, and it's easy to understand when someone is explaining it clearly. It's all thanks to you sir!

[jaspercarylalcantara]

This video helps me to understand the functions, limits, and continuity. It also helps me to understand how to get the domain and the range and how to graph the given functions. The way you present the topics were clearly and easy to understand.

[johndee]

Since I have background knowledge about range and domain this video helps me to recall what we us already tackled when we are jr. high and senior high. This video is very helpful to us because the way you explain every procedure on the solution made studying calculus easier.

[jay-romecerujano]

As a freshman engineering student, I really need this kind of video that is very helpful and a useful thing whereas many student like me could use to get some new and additional knowledge aside from having and reading our module, because this video is not only explaining every detail nicely but it is also a very helpful way for students like me that is having a hard time at understanding a certain lesson to have at least a place where we can go back to listen and watch it again until we understand and find what we are looking for. Since I'm not that good at self-studying (I'm sure, there are some too), this video will surely be a very helpful thing for us specially me to allow our lesson in Differential Calculus be at more ease to understand. Looking forward for more great videos of you, sir! Thank you! <3

[rosejanemagkawas]

Thank you sir for this presentation! This helps me a lot especially now that I'm making an assignment about functions. I can say that this video is worth watching because I've learned a lot.

[clarencemendiola]

This video really helped me to recall what we have discussed when we were in Senior High School. It helped me to understand some parts of the topic that Im confused. Thank you Sir for the well-explained presentation. God bless you, Sir.

[juliusgomez]

The presentation is clear, it helps the students be able to understand the topic. As an engineering student whose taking this subject, this video is going to be a great help for when I have confusions when it comes to the topic. Currently, we had just discussed this topic and with this video I can deeply understand the topic.
