3. Use Newton's method to compute a root for (1) f(x) = x -1 + sinx starting with $1 = .5, (2) f(x) = xIn(x + 1) - 1 starting with $1 = 1.7. In each case, how many iterations are needed to gain 5 digit accuracy after the decimal point? 4. Use Newton's method to compute an intersection point for y = In x and y = 23 - 2
