This is the second video im watching in a row, first was about angles (20min) then i also saw probability in play next, thought id check your channel and oh fudge yea, you got a subscriber. Epic content, wish id find you sooner. Ive been rlly confused with maths ever since i was a child, its not that i hate math, i love it but simply coudlnt understand, never got good teachers, but thanks to you i believe my era of being dumb in math is done with. Thanks by heart 👍👍👍
Hi at minute 20 and 49 sec, you talk about the dot product. But not what the dot product means. For instance, for the scalar-temperature, I can say a temperature of 100°F is Is hot compared to 32°F. But given two dot products 28 and the other 14 what does that mean in words? And it seems that the resulting scaler from a dot product operation for our be greater than the longest vector. Which also doesn’t seem to me much. My only assumption is that it’s a tool to determine if the angle between them is positive, zero, or negative. Given that I can establish that probably easier than a different method is the real use of the dot product? It seems you have to know the angle between them to calculate the dock product and if you know the angle between them, you know if the angle is positive, zero or negative already.
If A and B are two vectors, then: A× B = AB sinX unit normal vector on the plane. ( X= Angle between two vector), So A÷ B= ?, A^(--1) = ? Or inverseA=?
for me one of the hardest parts about math in general is the goddamn notation. it seems like every video i watch someones using different types of brackets for the same thing. even worse when it comes to vectors
Hi sir .A man ask me what is ur age and then ask me wether age is vector or scalar .How will I answer .How can we know that a given quantity is a vector or scaler .Thanx I m waiting for ur reply
