    it might be quadratic, let me check...

    well, since i designed it, i think its quite intuitive lol

    you have places to put in your data points; a quad only needs 3 data points to figure out; .....

    the "how many we need to find" box is for an additional 'x' data point to either test or determine

    this data doesnt match precisely to a quad tho; its close, but not exact

    i used the end points and the middle and asked it to determine the intermediates and it didnt match exactly

    i see could it be an exponential

    with up to 5 points here, we could try to match it to an x^4 graph..... but yes, exponential is a likely possibility

    no... not likely; the first and second and third points make a dip...

    i aint designed a cubic finder yet lol same principles; but with 4 poijts for reference and a new set of algorithms to figure out

    yes, all the info is better than just part of it :) you may have inadvertently left out some pertinent piece

    An object is moving along the x-axis with values of the velocity v in m/s at time t given in the table above. Given that the distance traveled may be found by calculating the area under a velocity/time graph, use the trapezoidal rule to estimate the distance traveled by the particle in the first five seconds.

    ....... well then, lets use the trap rule lol

    yeah i intend on using the trapezoidal rule after finding the equation of the graph

    why do the trap after finding an equation?

    the directions clearly sate; use this info and apply the trap rule... i see no need to complicate it :)

    but you can use the trapezoidal rule without an equation i believe lol

    the trap rule, as well as the simpson rule, and all the other numerical analysises are for estimating to a certain degree of precision what integration does with precision when you CANT integrate
