]]>As you know two points you can get the equation of the straight line in the form y = mx + d. Substitute that value of y into y = x squared to get a quadratic in x. It should be easy to factorise as you know (x-1) is one factor. The other will give the x coordinate of C.

]]>Do you have formulas for sinh(x + y) and cosh(x+y) ?

If yes, use tanh = sinh / cosh

Or go back to definitions in terms of "e"

]]>To start with, maybe putting some balls to hyperbolic space and simulating pseudo-physics...

But there happens to be zero practical/direct tutorials on how the space works in ground level. There are many "solve hyperbolic function" -things which might be useful if I already knew what to do.

* ** 1) ** To start with, as hyperbolic space contains "more" space than euclidian space, do coordinate systems differ somehow? What is the true way of specifying object's position?

* ** 2) ** Also, in order to make anything happen in such space, how is distance and linear transformation defined?

You can achieve mathematical layout by using LaTex. There is a tutorial on this here:

http://www.mathisfunforum.com/viewtopic.php?id=4397

And there is a site called WolframAlpha that will compute some integrals for you. It's here:

But that won't help if you're trying to learn how to do them for yourself. If you post a problem on the forum someone will try to help, but don't expect we're just going to do your homework for you

If you cannot create the right LaTex try saying the question in words. We can translate those for you and post up what we think you're asking.

]]>Thanks for posting that. I wanted to check the wording ... in particular "measured in years before 2008". t might have been 2 yearly rather than one yearly.

So (b) First measure is 7.019. t value from table is 25 so 2008 - 25 = 1983. Your answer is correct.

Second measure is 6.957. t value is 125 so 2008 - 125 = 1883. Book answer is correct. If the question said 6.992 your answer would be correct, but both posts show 6.957.

Text books do sometimes have wrong answers. Mostly a typo, but in this case it looks like the question was changed (maybe to make it easier) but the writer forgot to alter the answer. Then you have to look further along for the next answer ... stopping you from just going along to the next column.

Hope that helps,

Bob

]]>a) answer : is 2008-2009

b) answer is : 2005-2007

can you explain to me again in other way please
