4ii) Straigth-forward, you can just expand the first part and equate coefficients in terms of p and solve for it.

6) Vertical asymptotes are found when the denominator is equal to 0. Horizontal asymptotes are found when

7iii) What is the starting value of ? What is the final one?? To find these, set and respectively. Then split the summation such that you have two summations from and apply the formulae you found earlier.

Thanks a bunch, but how do you solve the inequality for part iv and for 7 what should I have got for part i.

For the inequality, the simplest way to go about it is to use the graph you have sketched and see for what values of you have

For Q7 part i you simply need to apply the method of differences and get the result shown on the RHS, if you do not get this then you go wrong somewhere.
