Question

Can anyone be my tutor? I NEED someone good with explaining and solving recursive and explicit formulas. Please comment!

Answer 1

Please comment to let me know...

Answer 2

:-(

Answer 3

I am prety good at math I could give it a try

Answer 4

It usually works better if you post a problem and include your best efforts at a solution.

Answer 5

Thank you @Dobby1 and @tkhunny I do not have a specific problem and I cannot think of one at the top of my head - I do not want answers I want explanations.

Answer 6

oh uhm then i dont know because it helps if there is an actual problem I am helping with

Answer 7

@Dobby1 I am doing a quiz and I need to explain the steps on how I solved this recursive formula:\[f(1)=35, f(n)=f(1)+f(n-1)\ for\ n>1\]

Answer 8

That is a specific problem...

Answer 9

ok let me take a look

Answer 10

hm

Answer 11

That is not really the question - hold one, maybe this one is easier:

Use the recursive formula that I gave you to make a table of values for 1 ≤ n ≤ 5. Show your calculations

Answer 12

ok so that means if you had a number line n would be somewhere in between 1 and 5

Answer 13

in other words n is no less than one but no greater than 5

Answer 14

so a list of numbers that n could equal is 1 2 3 4 5

Answer 15

does that make sense?

Answer 16

OMG, I am so sorry for not replying, I was afk.

Answer 17

So it would be 1, 2, 3, 4, 5?

Answer 18

@Dobby1

Answer 19

These kind of questions are easy to do if you make a table:
\[\begin{array}{c c c}
n |& f(n)\\
1 |& f(1) = 35 \\
2 |& f(2) = f(1) + f(1) = 35 + 35 = 70\\
3 |& f(3) = f(1) + f(2) = 35 + 70 = 105\\
4 |& f(4) = f(1) + f(4-1) = ... \\
5| & ...
\end{array}\]
and so on, taking previous values of f(n) from the table

Answer 20

So that would be the table, @Meepi ? Or is that an example?

Answer 21

It's the same recursive formula as in the example, you just need to calculate it for n = 4 and n = 5 still :)

Answer 22

I meant is that a table for 1 is less than or equal to n is less than or equal to 5? I'm sorry, I didn't understand. But I will try to observe what you did so I can try to do it myself. :-D

Answer 23

kay, it is a table for that - sorry for getting confused, but let me see what 4 is.

Answer 24

So, based on what you did, @Meepi :\[35+105=140\]so...\[f(4)=f(1)+f(4-1)=140\]

Answer 25

yep

Answer 26

Thanks. :-D
