I'm stuck on this exercise, I know I'm getting close, but I just can't see it
Prove by induction that .
Basically this boils down to showing that , simplified:
My right hand side simplifies to
So obviously I'm missing something and I'm afraid it's as trivial as possible, but I just don't see it at the moment
Hmm, ok, I thought it had to be:
Take for example
Now we need to show that , which of course is true.
I thought was analog to that? I fill in k + 1 in the LHS and add that to the RHS.
Is it possible you explain your answer a bit further? Would help me tremendously, apparently I don't understand it quite as good as I'm supposed to
Thats exactly what I was trying. I've identified what's going wrong by working trough another example. And it's actually very basic...
I fail to understand why, for example and in this case, why
Ah, I understand the latter one, could you please provide a pointer to ?
