Hi friend, I am sorry I didn't get to reply to your message the other day, I was actually busy and procastinated that I'll reply later but unfortunately I forgot. To be sincere I am very happy that you like my videos, it's Quiet stressful creating them, but it gives happiness and fulfillment when someone is appreciating your work, I must say sometimes I feel discouraged but once I remember you and other friends who like th videos, I get encouraged and work toward preparing more. I have loved math right from childhood, it makes a lot of sense to me, it's just to interesting, I wonder how some people find math boring, they are great in what they love doing, everyone is perfect in doing what they are interested in. Thank you so much

And please I want to ask you, you know English is not my mother tongue, please what's the meaning of the word "procastined", is it the past tense of "procastinate", If it is then why not 'procastinated"

@@MathandEngineering my (probably correct) guess was that it was a simple misspelling of procrastinated. However, I discovered that it’s an actual obsolete variant. (From wordnik search for procrastine.) English is full of such archaic, obsolete and obscure words. My language appears to be in a race to the bottom as it were: deep, rich and subtle words and ideas are continuously replaced by the simpler ones. A few different groups will use such English words including highly educated non-natives who pick up the words while reading older texts. There are words from passages in the King James Version of the Bible that lack entries in regular dictionaries today. This is a significant problem because it becomes nearly impossible to understand older texts when words are being rapidly replaced and even redefined due to social fads, as well as philosophical, political and ideological movements. These things have effected math and science as well. Bertrand Russell addressed this problem quite forcefully in his essay “On Denoting.” He would have argued that this problem is not confined to a single language-and of course he saw its logical/mathematical implications. So sorry to give an essay instead of a simple answer. It just means “procrastinated.”

Yes thank, I like the way you answered. if you didn't explained like you did and just told me that it just means "procastinated" I would have asked for an explanation. Thank you sir

|BT| = ? ??? There is no T. Just t. So it is unsolvable.

[@MathandEngineering]

Well sir, I don't know why you think T is different from t. T is the capital form of t. The only time we can differentiate between T and t, is when we have t and T used in two different places in the same subject. But in the Question, there is only t. So there is no reason that we should think it is different from T. Or does it goes against any rule in your place?

@@MathandEngineeringMaths and science are routinely case sensitive. And various fields have various conventions regarding what symbols should be upper and what should be lower case.

[@MathandEngineering]

Ok thanks sir, I understand. I also just recalled that, t is the small form of T only in English language, But in math it's not applicable, thanks 👍 so much I'll adjust that
