Level sets and level curves (Part 1)

Hello everybody. This video will be a little different from the rest of my videos. This topic is based on the concept of level curves and level sets.
Though this will act as the foundation for a future economics video of mine, the concept has varied applications in the subject of mathematics and other subjects like geography as well. Throughout the 2 parts of this video, I will be using easy comparisons to explain the theory.
If you have any doubts regarding this topic, please feel free to contact me in the comments section below and I will most definitely get back to you. Feedbacks and positive criticisms for improvement are also most welcome. If you appreciated my video and would like to encourage me, then kindly like this video. Also kindly subscribe to my channel for future tutorial videos. More videos coming up soon.....Thank you so much!!!
