    Thank you! I’ve had difficulty in understanding L’hopital’s rule, and your tutorial is a big step in the right direction.

    The most soluble and miscible proof and the smoothest of logical derivation for a simplified,yet atomic scale interpretation and visualization. Absolutely stupendous!!!

      I'm a math teacher myself and I have made it a point in my career to also have exemplary handwriting. It makes math easier to follow for students if they are not guessing what you just wrote on the board. His explanations are clear, his pacing is perfect, he gives context before diving in. This guy is a natural. I only assume he's a college professor/high school teacher.

    I love the proof. It is an ‘ if A, then B’ proof. You start with part of B and jump back to A and use that information to rewrite the expression. When the rewriting from A maths the writing of B, the proof is done.
    Thank you Doctor. The proof is simple and shiny.
    Looking forward to the next proof.

    Thank you so much! this really helped me understand the rule and it's a really elegant proof, and in general your channel is incredible and I cannot believe you don't have more subscribers. However, I've heard that l'hopital's rule works in other cases besides 0/0 like for example infinity*infinity - have I been misinformed or is there some way to further derive other applications of the rule?

    • @PrimeNewtons
      @PrimeNewtons  2 ปีที่แล้ว +1

      Thank you. I hope some day the channels grows sufficiently. Yes it works for any of 'the seven deadly sins'. I have a video of all 7 forms. However, the function must be rewritten as a rational function to apply L"Hospital.

      @christophvonpezold4699 2 ปีที่แล้ว +1

      @@PrimeNewtons ah ok, good to know - I actually did watch your seven sins video, so what your saying is that basically all indeterminate forms in some way are derived from 0/0 and as such can have l’hopital’s rule applied to them if expressed as a quotient?

Also on the same graph, sketch the corresponding f' (x) ; of course with f ' (a)= zero. ..... then also draw th same for a carefully selected g(x).. discuss. what you see. ...

  • @kingbeauregard
    @kingbeauregard ปีที่แล้ว +5

    I believe in L'Hopital's rule, and I believe in your proof. I am still working on understanding why it makes sense in concept, and I'm almost there.
    If both numerator and denominator are racing toward infinity, the question is which one gets there faster. In other words, how do their derivatives compare. And since we're heading to infinity, any finite conditions (for example, a constant added to the top or bottom) cease to matter. I think my logic holds up.
    But when it's 0/0, my logic is a little flimsier. I feel like, if your function is approaching zero, then the reciprocal of your function is approaching infinity, so the same "infinity" logic might apply. But I haven't convinced myself that it's a valid argument.
