Hi all I have these problem on my test review and even after guessing one right I have no idea how one would arrive at that answer so your help is greatly appreciated. 1. The problem statement, all variables and given/known data 1.find the limit as x approaches 0 in the equation[(3/x^4)-(4/x^2)] 2.Use Newton's method to find the positive value of which satisfies . Compute enough approximations so that your answer is within .05 of the exact answer. 3. The attempt at a solution For the limit problem I simply tried taking the derivative of the two equations and subtracting them which gave me 0/0. I know the answer to the problem is infinity but I have no idea how one would arrive at that solution? On the second problem I really dont have a clue. I dont know how to apply that to the normal newtons method formula to a problem worded like this any help is appreciated.
