2. By "infinite surds" do you mean infinite series? And... technically, you should only have your portfolio for 10 days...

I'm not doing this portfolio, but a couple answers to your questions:

If it's square root of 1... isn't it still 1?

integer - numbers such as -1, 0, +1, etc. (no decimals)
exact value - fraction or radical (no decimals)

Hello!
Does anybody know how to do infinite surds? I've been struggling for the past two months trying to find out WHAT an infinite surd is in order to do my portfolio...the first check of it is due tomorrow and I still haven't been able to answer a SINGLE questions... I've tried doing them on my calculator however the answer given is wrong! How am i supposed to do this?!?!
Here are the questions:
a1= sqrt1+sqrt1
a2=sqrt1+sqrt1+sqrt1
a3=sqrt1+sqrt1+sqrt1+sqrt1

Find a formula for an+1 in terms of an.

Calculate the decimal values of the first ten terms of the sequence--> How do i do that on the calculator?!
Use your results to find the exact value for this infinite surd what is EXACT VALUE how do i find it?!

next section:

consider the general infinite surd
sqrt k + sqrt k + sqrt k + sqrt k where the first term is sqrt k + sqrt k. Find an expression fot the exact value of this general infinite surd in terms of k
--> How do i find that?!?!

Find some values of k that make the expression an integer what is an integer?! (yes I'm that bad in math--PLEASE HELP!) Find the general statement that represents all the values of k for which the expression is an integer...how do i do this?!

I would really appreciate help as soon as possible!!! Thankssss

Some idiot put his work up on the internet, but since its there there is no harm in using it as long as you don't copy it at all.

(It isn't perfect anyway; his answers to the last question of the coursework are poor, but all the maths is correct, so it will allow you to get most of the marks)
