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.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.
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 don't have a clue. I don't know how to apply that to the normal Newtons method formula to a problem worded like this any help is appreciated.
