Can titanium made thin enough or designed a certain way to be used as a cover for a push botton switch? Such as the one made from plastic in the flashlight below. http://www.photonlight.com/PhotoDetails.asp?ShowDESC=N&ProductCode=P1-keychain-LED-flashlight The titanium would cover the...

Hello,the <Diamond> + F1 menu allows me to plot only Y= graphs. I just want to ask if how do I graph in terms of y? is there anyway or you need to really graph it in terms of x? thank you very much...

Hello, I wish to write a function that takes in 3 arguments and outputs 1. I want it to be a saved function so that I can call it at will like cos() or ln() How do i go about doing this? I am unsure of the syntax. Let's say it is really simple like: f(x,y,z)=x+y+z So from the home...

It says (the TI site) that the TI-89 Titanium can manipulate symbolically and what not. Well I just have 2 quick questions: let's say I punch in some equation like \frac{dE}{dt}=\dot{Q}-\dot{W}+\sum_i\dot{m_i}h_i-\sum_e\dot{m_e}h_e 1.) I could somehow select W (for example) and the calculator...

ti-89 titanium urgent help I have been using the ti-89 over over a year now and have never come across this problem. I went to the numeric solver category in the APPS menu and put in a numeric value. When I went back and put in an expression to be factored ex. (x^2-36). It gave me the answer...

Homework Statement A sample of titanium dioxide (TiO2) weighing 1.598 g is heated in H2 gas to give water vapour and 1.438 g of another titanium oxide. What is the formula of the oxide produced? TiO2 (s) + H2 (g) TixOy (s) + H2O (g) (unbalanced) The solution posted is as follows but...

hi i wonder if anyone has an idea about or have links for published papers about the behavior of bulk titanium carbide (TiC). thanks

The <Diamond> + F1 menu allows me to plot only Y= graphs. How do I plot a graph of say, y^2=x+4 ? You cannot plot y=Root(x+4) because you would miss the negative part of y. If this is the only way to plot such graphs, how to you tell TI to plot a y= +/- Root(x+4) ? Thanks.

How to enter negative numbers in Ti89 Titanium?? This is so hard. I wonder whether I need more training in Google search or is it that the Ti89Titanium has a very very poor Knowledge Base and Tutorial. How do you enter a negative value? During my search, I noticed that the Ti89 uses a key...

You have 2 balls. Both are identical in size and mass, but one is made of gold and is hollow,the other is not hollow and made from titanium. Find out which is which ball, and let's say both are covered with a black paint that is anti reflective, heat/electricity insulator. You can't use any...

Hopefully I can throw this question in this section, sorry if it should go elsewhere. Seeing as I am studying in engineering, I thought others may have the same calculator and be helpful. Anyways, I was wondering if there was a way on this calculator to show say 1*_W (unit of watts) in terms...
