well i wish my physics teacher was like you. explaining everything and not ASSUMING that we all know how to do it....

[UnexpectedDianne]

OMG! THANKS!

We have a very terrible professor, who doesn't explain anything to students and whenever we ask him a question he calls everyone Idiots...

Anyways, Thank you so much! <3

@l00seg00tyh0les I'm assuming you are in my class.

@themilkmister Thankyou <3

When the title says vectors, I expect to learn about vectors. If someone does not know basic trig, redirect them to another set of videos. Anyone learning vectors is expected to know how to use sin cos and tan. Also spending massive amount of time repeating every single line 4 times is how the 15hours came about. THIS IS AN ONLINE VIDEO, YOU ARE ALLOWED TO REWIND IT. If you are going to repeat something, say it in a different way, repeating the same exact wording (probably cue cards) is useless.

OK so people, realize that this guy spends more than 850 minutes, about 15 hours on vectors, your actually professor has about 5hours to teach this AND stuff way more advanced than this. I skipped to ep35 and he still hasnt taught the basic formula to solve a vector. This series of videos spend about 20 videos or less of actual vectors and 65videos on basic junior high school math. (intro to trig, Pythagorean theorem, SUBSCRIPTS, etc)

@cacaloveforever i agree...

@badgerbirk The retards called, they want their friend back.

@iceheart540 LOL and u are searching for EDUCATIONAL HELP? logic?

[Buttzy89]

I LOVE YOOOOU!!!!
