Ummmm..
Just Curious..
But what does a triple and quadruple differenciation of a function signify graphically??
I know its increasing or decreasing with first derivative, second tells concavity that means how much..
But whats the role of 3rd and 4th???

Best ResponseYou've already chosen the best response.3spose you wanted to create a polynomial that moved like the sine function both functions would have to MOVE in the same manner, and all of their derivaties would have to be equal

Best ResponseYou've already chosen the best response.2hey @amistre64 I think it's the third derivative that's the jerk?

Best ResponseYou've already chosen the best response.2Well... f'(c) is the slope of the tangent line at the point x = c f''(c) is the concavity of the graph at the point x = c f'''(c) is the rate of change of the concavity??? XD

Best ResponseYou've already chosen the best response.0@terenzreignz As much of a guess that was it actually is the right answer!! :D :P

Best ResponseYou've already chosen the best response.0concavity is the rate change of the slope, so all that is saying is the rate change of the rate change of the slope, which we can extend to all derivatives.

Best ResponseYou've already chosen the best response.3sin(0) = 0 ; P(x) = 0 sin'(0) = 1 ; P(x) = 0 + x sin''(0) = 0 ; P(x) = 0 + x +0x^2/2! sin'''(0) = 1 ; P(x) = 0 + x +0x^2/2! x^3/3! sin(x) = P(x)= \(\Large\sum_{n=0}^{\inf}\frac{(1)^n}{(2n+1)!}x^{2n+1}\)

Best ResponseYou've already chosen the best response.3i was just demonstrating that the successive derivatives of a function define how it is moving at a single point, and that 2 function that are equal at a single point, and equal at all their successive derivatives are the same at that point. Since polynomials are so much easier to play with, if we can construct a polynomial to work from, that converges (is the same), at a point or range of points. Then mathing is so much simpler
