    Hey guys, I originally made these youtube videos to help my classmates before a Calculus 2 test that we had 3 years ago. But seeing how far it blew up really encouraged me! I've decided to upload more math tutoring vidoes to help you guys! I'll be sure to upload more math tutoring videos focusing on Calculus 1, Calculus 2, Geometry, Trigonometry, and Algebra. Thank you guys so much for all the love and support! I am so happy that I could help you guys! More videos coming soon, I promise.

    I am in Calc 2 right now and had no idea when to use the different methods until I watched your tutorial. I spent the last two days in the library looking for hints on the internet and nobody made any sense. This video makes everything so clear. Thank you!!!

    Hey guys, so a lot of people were asking what a strip is. A strips is the rectangle that I draw from the function to the axis of rotation. Like someone else in the comments pointed out, the strips are the rectangles or bars that are used to make approximations. The strip rotates 360 degrees to form a 3-D shape from 2-D rectangles. When you create infinitely many rectangles in the bounded region we can get closer to exact values.

    Oh my god, it's a very difficult material but you manage to simplify it. What a phenomenal video. You've just helped me to understand the materials under 15 minutes. This video deserves to be on top of the searching lists so that people can notice it. You have just saved me and my friends to comprehend the topic. Hopefully, you'll become one of the best math youtube channel tutorials in the future. I'll be watching A.S.A.P. Thank you so much 😃.

Calculus 2 is known to be one of the hardest classes you will ever encounter but you did an amazing job at explaining it. I am going to show this to my teacher because it's just too good. Thank you for the hard work you put into this video.

  • @thaumaston7
    @thaumaston7 Před rokem +1

    Excellent! It's been a while since I dealt with solids of revolution from calc 2, but I needed to review this topic for something. I programmed the formulas in my calculator, and the only thing I needed to remember is when to use washer vs shell. This video cuts to the chase and is more helpful than any other I've seen. However, I think there's a simpler way to think of it. I only have two programs for this in my calculator -- one for washer, one for shell. There's no need for "disk". Disk is just a variation of washer. In my washer code, I enter a value for any separation from the rotating axis. When there's no separation, the value is 0 (creating the "disk"). This is also how I've seen it taught in various calc 2 texts -- just washer vs. shell. I think it's easier to think of two choices rather than 3.
