Here are some of my teaching materials which includes video tutorials and slides that I have made and shared with the world. During my spare time, I like creating such material, as I find this to be a way of giving back to the community.
Here is a recent presentation I did on non-linear optimization applications in financial mathematics that I have shared with my classmates.
Video Tutorial on Introduction to Differential Equations
6th Grade Mathematics ~ tutoring my cousin over the Skype video calls. I help my younger cousins with their school work via Skype. I screenshare my window that I write with my digital pen so that my cousin can see what I write during my explanations. Sometimes I screen-record the entire call and share the video on my Google Drive so that they can review the lesson later. You can hear my cousin Okitha's voice in this video who lives in NY (who is on the other end of the Skype call) while I was teaching him from Morgantown, WV.
