Find the arc length of the graph of y = x from x = 0 to x = 3 using calculus.

  • calculus -

    ∫ √[1 + (dx/dy)^2] dx (from a to b)
    first, take the derivative of x and plug it into dx/dy, square that
    then, add 1 and square root it
    last, take the antiderivative

  • calculus -

    and of course, plug in the numbers
