Question 3 The linear function f(x)=ax+b is identity function if a=b=0,  a=b=1, (a=1,b=0)

What is the question here?

#202 Re: Help Me ! » Function and limit mcq » 2017-04-04 21:13:30

X^2+y^2=4    is function or not a function

It is a functiion.

Question 2 The function f(x)=ax^2+bx+x has Maximum value if        a>0  ,a <0, a>1,a>2

Hmm, you need to find the max. and min. value of a quadratic equation. The max value of a quadratic equation is as follows:

a>0-∞
a<0--D/4a
a>1-∞
a>2-∞

Question 3

???

Yes, no doubt. He is the creator of everything.

The petals of flower following fibonacci sequence is not there.

But maths learning from nature interests me very much. It is a very good sort of learning. BTW do you know the relationship of Fibonacci series and golden ratio in nature?

#209 Re: Maths Teaching Resources » Maths Books » 2017-04-03 22:18:30

My BMA book contains difficult problems on combinatorics too.

Hmm good, after some fresh works of maths and computer, you can easily roam about in the forest. Nature has also baeuatifully described maths, Relationing between the Fibonacci Sequence and Golden ratio. You may have observed them.

If danger was the only consideration then I would not go anywhere. There are dangers all around me. Even if I were to lock myself in my apartment I would still not be safe. We do not have safety on earth and death comes to us all. Part of it is my training, I know that death is not the end, it just a transition and I will be reborn again.

I like hiking and though I am afraid of the jungle and the swamps and the forests, a person should not let fear control them. I prepare well to minimize the danger and maximize the fun and the beauty. It takes skill and work but it can be done.

Yes, we should be brave enough.

#212 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-03 21:35:31

Then If you know yourself that the forest is dangerous, why do you frequently go there?

#213 Re: Maths Teaching Resources » Maths Books » 2017-04-03 21:31:09

Yeah, Combinatorics means Permutations and Combinations. I think I'm very good at them.

We are allowed to carry a weapon here in Florida but I have never been in a spot where I would have had to use it. Killing anything is against God's laws and I would not do it unless there were no other possible options. As I said the animals avoid me.

hmm, good job

#217 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-03 21:16:19

So, if you love forests so much, move but with a gun( though killing of wild animals are banned nowadays).

#219 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-03 21:08:36

Hmmm, I knew that, Ocala national forest is very famous.

yes, I live right on the outskirts of it and if I step out of my balcony I am immediately in the jungle.

You live just beside the jungle. I just searched out what dangerous animals were there in this forest and a direct google answer came out from wikipedia which I am going to quote here:

Wikipedia wrote:

The Florida black bear population has its highest concentration here. alligators, white-tailed deer, wild boar, and numerous small animals, including squirrels, bats, coyote, gray fox, red fox, opossum, raccoon, river otter, bobcat, skunk, southeastern pocket gopher, and nine-banded armadillo can be found as well

I would advise you not to go inside the jungle at this old age as, if any animal attacks you in the age of 96, you will not be able to run or hide, and you may die.

#220 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-03 21:01:00

Then I guess you roam about in Ocala National Forest, right?

#221 Re: Maths Teaching Resources » Maths Books » 2017-04-03 20:57:21

But I don't see him posting any posts. Has he become a dead member?

#222 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-03 20:54:05

But when I entered Forest in Florida in google images it showed these photos:

images?q=tbn:ANd9GcTCOuXz9-6qIj0ynCBwsbSHgw-d8EeuZIK5ZGK8voqSNDkr_Vh4jQ




Anyways, I will ask you a question. Do you live in Tallahassee?

#223 Re: Maths Teaching Resources » Maths Books » 2017-04-03 20:46:15

I forget solutions too after a day or two. You should get into the habit of keeping notes.

Yes, you are right.

gar has this signature.

The palest ink is better than the strongest memory.

But when I visited his profile his signature showed this:

"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  - Buddha?

"Data! Data! Data!" he cried impatiently. "I can't make bricks without clay."

But... in the jungle the sun's rays get filtered out through the huge trees covering the sky and it gets shady under tall trees.
