text: ne can find things like the sum of the cubes of roots of a polynomial using Vieta's formulas and then applying this mathematician's identities about symmetric polynomials.
full_question: ne can find things like the sum of the cubes of roots of a polynomial using Vieta's formulas and then applying this mathematician's identities about symmetric polynomials. Joseph Raphson is the real developer of a technique named for this man, in which one repeatedly finds where a tangent line intersects the x-axis, as part of a (*) "method" to iteratively approximate the roots of a differentiable function. This mathematician famously claimed that his success came because he "stood on the shoulders of giants." Controversy exists whether this man or Gottfried Leibniz should be considered the inventor of calculus. For 10 points, name this mathematician whose Principia Mathematica laid out his three namesake laws of motion.
