Failing Calculus? Bad Grades? Run out of luck? Better Call Sal!

Why can't professors in my university be as good at teaching those things as you are?! Thank you!

[potatoa]

saving my pre-calc grade one video at a time

[quinntaylor]

do these videos ever end, or are they CONTINUOUS!!!!

Hello, this is solving graphically... But what abt solving "mathematically"?

[satyvirjasra]

If i make my own university, rather than hiring lecturers i will show students Sal's videos i am sure students will do 100% better than other universities. Bloody lecturers be like "Anyone has any questions?" and they don't look in the direction of student with hand raised.

Ur teachings are really excellent sir they are easy to understand.

[Raggy]

You are literally a life saver❤️ thank you so much:)

I thought calculus in one of tough parts of maths but after seeing these videos now i think not any more

[Samantha]

thank you! This really helped me understand the basis of my calc lesson.

[kimberlysamantha]

I appreciate this so much. Thank you for taking the time to post this video and really all your videos.

How is this concept extended when the limit goes to infinity? You can't really find a neighbourgood/range for x (i.e. delta) for x = infinity because infinity isn't a "point". Or how do they deal with this? How do they define infinity and adapt this rigurous definition to being rigurous when x goes to infinity with epsilon/delta?

What about pointed part of a curve is it continuous?

[sarahbardeskar]

"What i want to do in this video" is thank u for it!!!

I literally only attend my calculus class to sign the attendance sheet then I run back home to watch this guy's videos to learn the lesson. The only notes I write are the titles of the sections (I can't understand what teacher is saying half of the time.)

[Tasniaaaaaaaa]

I only go to my calc lectures to get attendance points..i consider you to be my actual calc teacher though :P
