2 (3) Use Newton's method to estimate the solution to e" =x+1 Use r = 1 for your initial guess, and apply Newton's method twice (n=3). Show your intermediate steps as well as your final answer. (4) Find the most general anti-derivatives of the following functions. (Notice I'm asking for the anti- derivatives, not the derivatives. I'm asking for the function F (x) that satisfies F' (x) = f (I).) (a) f (x) = 5ex - 7 sin x (b) f (x) = 172- secr tanr (c) f(x) = 1-vi
