I have never seen like u intuition based teacher ❤
Wonderful
You are such a good teacher!
thank you, just thank you.
5,000 viewers couldn't make it to part 2.
stop watching TV..spending hours on facebook,twitter etc..just spend some time thinking about what you want to do with your life….and you will get your inspiration..just like that…anyways…the best motivational speaker in youtube(in my opinion) is Eric Thomas…he is outstanding…you should check his channel out and i believe that you will learn a few important things about you!!!!!!!!…good luck
Where did the negative sign go from the u substitution?
it already is a shitty life though
Think about how shitty your life will be if you completly ignore studying.
i need help with getting inspired to get work done and studies done
thank you for posting this sal i'm in vectors using integrals now and this is a great reviewer for me ^^
Sal your'e an incredible teacher and I can;t thank you enough for your help. From Trigonometry to the history of Napoleon Bonaparte you make school so much easier for me. Not all teachers are able to explain a subject in the short amount of time they have plus with so many students on hand, but when I'm introduced to new material my first impulse is to find khanacademy and learn it correctly! Thank you so much again.
Sincerely, the most appreciative student on your roster
