    Hey guys, I originally made these youtube videos to help my classmates before a Calculus 2 test that we had 3 years ago.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.

    You teach calc like my dad showed us in high school. We ended up getting a BIG head start, I didn’t even realize it at the time. I always preferred the straight forward method.

    I'm majoring in biochemistry and my degree requires I take Calc 1 and 2. Currently in Calc 2 and all I can do is thank God for leading me to your videos. Your explanation and visual aids are a godsend. THANK. YOU for breaking the content down perfectly. Easy to follow and easy to understand.

    Pls.if the region bdd. by x^4 , 2x^2 ;
    [ 0 , 1 ] rotated around y=0.5 . What is the Volume?

    • @AshleyTheMathTutor
      @AshleyTheMathTutor  Před 2 lety

      I will look back into this and respond
      later with results once I solve the problem myself

    • @AshleyTheMathTutor
      @AshleyTheMathTutor  Před 2 lety +1

      Okay so i did it and I got 7.1558.
      So lets make y1 = f(x) = x^4, and y2 = g(x) = 2x^2.
      So first, since the rotating axis is y = 0.5. g(x) has a smaller distance to the rotating axis so r small disk is 2x^2 + 0.5. f(x) has a larger distance to the rotating axis so r big disk is x^4 + 0.5.
      So, When you set up (r small disk)^2, you get (2x^2 + 0.5)^2, which is 4x^4 + 2x^2 + 0.25. When you set up (r bigdisk)^2, you get (x^4 + 0.5)^2, which is x^8 + x^4 + 0.25. So when you do (r small disk)^2 + (r big disk)^2, you get x^8 + 5x^5 + 2x^2 + 0.25.
      So now, we have to find pi * the integral of x^8 + 5x^5 + 2x^2 + 0.25 from the boundaries 0 to 1. That is 7.1558.
