<p>Well I've been taking alot of Math 2 practice tests, and there seem to be quite a few (x,y,z) distance questions. I'd like to program it into my calc so that it doesnt take as long during the test. Is there a way to do this, and also program the arithmetic sequence equation. Any help would be greatly appreciated!</p>
<p>Uh... it doesn't take long to do 3-D distance formulas... and why not just memorize the equation?</p>
<p>I probably will do that but I would like to program it for a just incase type of scenario.</p>
<p>I thought about programming every formula but blah, it'd waste so much time during the test.</p>
<p>Do this - memorize it and as soon as you get your exam, write it down so you won't forget it =P</p>
<p>it's just the Pythagorean Theorem with another argument...</p>
<p>??</p>
<p>Just do 6 prompts for the coordinates of both points, do the formula with the 6 variables, and display the answer.</p>
<p>What Noober said. Given the points (a,b,c) and (x,y,z)</p>
<p>Prompt A
Prompt B
Prompt C
Prompt X
Prompt Y
Prompt Z</p>
<p>sqt((a-x)^2+(b-y)^2+(c-z)^2)=(arrow) D</p>
<p>Display D</p>
