A small warning? If they forget the rule then it's okay, but if they do it intentionally they should be dealt with anyway.

Well, you said IIB, which is probably idiot.

Make a rule that unless someone has made substantial effort, you can't give a full solution.

That's just plain abnormal, unless the function of your program involves it stopping.

I doubt that we will be extinct. By the 3000s, we will be so technologically advanced that no one can imagine.

But you did not describe your method. Did you just guess?

#437 Re: Help Me ! » Constant of Integration » 2014-05-23 13:52:52

An indefinite integral or antiderivative has no specified limits for the integration. For application to specific problems, boundary conditions must be applied to the result in order to arrive at a specific value for the integral. The uncertainty in the value of the indefinite integral is expressed in the form of a constant of integration which is not defined by the integration process.

I don't think you need a calculator right now though.

Why would you need to round? These are all integers.

I think the correct question is if anyone does not have problems with motivation. It is very common because of several reasons:
-you may like the thought of learning math rather than actually learning it (this goes away over time)
-you may not like math a lot (I think this does not apply to you and even if it does it usually goes away with time)
-you are not used to studying intensively (this is very common and I think it is one of your problems - you obviously haven't studied so hard in the past so it will take time to get used to it, but it will happen)
-you want to solve math problems but don't want to learn the material for it (this applies to you but the biggest problem regarding this is that you decided not to do any problems. I suggest you learn math and do problems alongside it, even if it's only a few problems to save time)
-you want to learn higher mathematics like calculus and are not interested in the prerequisites (this happened to me but after a while I enjoyed learning it)

Suggestions:
-keep trying
-start with less studying per day and then increasing it
-do some problems alongside, enough to remember the material and not to use up a lot of time
-increase your motivation by thinking that math is exciting, you will soon be learning calculus/differential equations etc, you will go to university etc

Don't worry - all of it goes away with time. The biggest mistake people make is that they face a few difficulties and they stop. Make sure you do not do that.

Good luck, I am sure you can do it!

What didn't you expect?

Hi zetafunc;

That is correct!

Hi Stefy;
I think you perhaps didn't understand the problem, because we are getting different answers and mine agrees with zetafunc's.

I'm searching for a good problem from my database, but I am mostly finding routine ones (I forgot to sort routine and difficult problems on the set of problems I am looking at).

Here is a problem with OK difficulty:
6. A right circular cone is inscribed inside a larger right circular cone with a volume of 180 cm^3. The axes of the cones coincide and the vertex of the inner cone touches the center of the base of the outer cone. Find the ratio of the heights of the cones that maximizes the inner cone volume.

They're a lot stricter over here then.

I'm probably not going to come and ask you if you are zetafunc, because you are at least a few thousand miles away. But I did come to both of Oxbridge sometime back - I really like their tutor system.

#443 Re: Introductions » Let us welcome zetafunc. » 2014-05-23 09:09:58

Nice. smile

Are you going to a Russel Group university?

I will try to think of some rules which aren't already in place.

I think we need a homework template which includes:
1. Homework Problem
2. Relevant information (formulas, theorems, equations, concepts etc which may be helpful in answering the question)
3. What you have tried so far (even if fruitlessly)

#445 Re: Help Me ! » geometry » 2014-05-23 09:06:37

Hello.

What have you tried so far or what do you think might be relevant information for answering the questions?
