I need some help with mathematical induction. It's driving me insane.
Use mathematical induction to prove that:
Basis step: Prove 1 exists in S.
n = 1 LHS =
RHS = = 1/3
So 1 exists in S
Assume k exists in S. We must prove k+1 exists in S
After this i just get lost, i think i have a problem when trying to perform arithmetic on it. Any help would be much appreciated.
I also have another question:
Find a fourth order polynomial with integer coefficients for which is a root.
SO we have
any help would be much appreciated!
For the second part of your question, you've got the right idea, but you need to be careful doing the algebra:
A tip for these boards: don't ask two questions in a thread. Someone comes by and answers one of your questions (as Tonio did), and then it looks like your question is answered, so no one sees your second question. There's no problem with starting two threads or even more, especially with two very different questions like you had in this thread.
