    The first principle is to watch all the videos by Prime Newtons! ❤🎉😊

    *_Never stop learning._* Advice I liked to give my own students. And when you master the understanding, you can more easily do word problems.

    What I like about this is, the same skills by which you find the derivative will come into play again when you do epsilon-delta.
    For a more general proof of the derivate of x^a, I had to resort to logarithmic differentiation.

    i did this by using newton's binomial theorem to expand (x+h)^(1/2) but then i realized you can just multiply by the conjugate 😅😅

    All first principle videos: Square root, all arctrig except arccot, plus some other various functions. Gotta say, I feel like a bit of a teachers pet doing this, he has a playlist. But its here for the record too

    I've always wondered: why does the limit definition give the slope? Perhaps I never fully understood it, l'm in Calc3 now, but it seems like you'd get 0 in the denominator, of course that's undefined. Logically, it makes sense, but it's just never worked conceptually in my head.

    • @Nameless-qe9hu
      @Nameless-qe9hu 5 місяців тому

      It’s the (y2-y1)(x2-x1) definition of the slope of a line at two points very close together. The goal is to get the “h,” which is technically nonzero, to cancel so that there is no division by 0 when you approximate “h” to be 0

    ... f'(X) = LIM(h -> 0) [ SQRT(X + h) - SQRT(X) / h ] ... [ rewriting the denominator in its original form ... h = (X + h) - X ] .... LIM(h -> 0) [ SQRT(X + h) - SQRT(X) / ( (X + h) - X ) ] .... now treating the denominator as a Difference of 2 Squares as follows ... h = (X + h) - X = ( SQRT(X + h) - SQRT(X) )( SQRT(X + h) + SQRT(X) ) ... observing a common factor ( SQRT(X + h) - SQRT(X) ) between numerator and denominator, so after cancelling this factor we obtain the solvable LIMIT form ... f'(X) = LIM(h -> 0) [ 1 / ( SQRT(X + h) + SQRT(X) ) ] = 1 / ( SQRT(X) + SQRT(X) ) = 1 / 2*SQRT(X) ... the derivative of f(X) = SQRT(X) ...
