Sir, you explain the content of Maths very good. Please keep on making videos on vectors and vector functions, if possible. Also Calculus videos would be truly appreciated. You a great teacher. GOD BLESS YOU.

again, how the hell does a 6 minute video explain better than my teacher talking for 1:30 about the same concept?

Thank you! I was confused that why don't we include zero when we write the intervals. Finally, I came across a video that explains why this is the case. May God bless you. :)
