Thank you Professor Strang ,you have helped me a lot.

'If I knew where we were (22:58) mathematics would even more useful than it is...which would be hard to do!' This guy is fantastic.

can someone plz tell me if there was a reason he didn't mention a critical number exists also when the function is undefined? also, in his example from home to mit, why is b constant????

can someone plz tell me if there was a reason he didn't mention a critical number exists also when the function is undefined?

[savadelis]

@rr5001 i think because he was using sinx and cosx. always defined in his beginning examples

God bless you Mr. Strang!! Thank you very much for your efforts...

I am taking a second look at calculus as I prepare for graduate school and your videos have been most helpful! Thank you!!!!!!!

This is a Hats off to the Calculus Master. Durring my engineering this was just a night mare. I now love calculus after viewing the three parts of this vedio series. Thanks to you.

To increase the reach to remotest areas of the world there are lots of breakages that happen during the sessions. It would be good if these vedios could be available for lower bandwidth connections too.

A BIG THANK YOU!

nice this teacher explains this pretty well.

The second derivitive should be 6 not -2.  d^2y/dx^2 = 6,

WILL SMITH IS AWESOME.

@NeoNaziMexcanJew

Will Smith.

Point taken though

[x1x2x3ct]

but those are just words... the graphs are telling us much more than the words do.

i could say the same as zik667, my teacher had a post doctor at a french institution at math teaching and still hadnot that good didactics. MIT rules, i wish i could study over there. Im brazilian and i have my engineer course at UFSC - Santa Catarina Brazil

[zik667]

I wish I had calculus like this, my teacher was a post doctor but he had no fucking didactics
