Calculus 2: Integration (1 of 9) What is an Integral? What is Integration?

In this video I will explain what is and the difference between an integral and integration.

Next video in the series can be seen at:

You are truly a gift to mankind.. I'm not kidding. I've never in my life seen a concept explained so well.

This 7 minute video taught me more than 6 classes of calculus

Any intelligent fool can make things bigger and more complex . It takes a touch of genius and a lot of courage to move in the opposite direction . <3 . Albert Einstein .

Very good, gentle introduction to integrals. Very good indeed. Now, let's move to the real definition of Integral. Let's try to find an area under the curve.

thank you thank you so much sir i really needed an explanation for the integral

[karies]

Thank you so much. I am a university student from South Africa and your videos really help A LOT. I'll surely recommend them to my friends.

Said it before and I say it again, you are indeed a wonderful educator, keep up the good work.

thanks for this awsome concept . I never have heared such a brief and elaborated concept before . Concepts are becomming crystal clear now .Thanks a lot

Another nice video. Would it be of interest to note that integration is a method to exactly calculate the area under the curve? In your example, (2x-4) is the height of an infinitely narrow rectangle with width dx. The "S" symbol stands for Sum and is Liebnitz' notation from his development of The Calculus, concurrent with Newton's work.

Can you explain conceptual relationship between slope and "area under the curve". I mean, how come these two are related under a certain operation.

Basic integrals can be found in calculus 1 as well, no?
