What are you trying to solve for? Do you want a program to solve this for you?

SonikkuUSA is right about the comma. Also, after the first "EndDlog", you have to add "expr(a)->a". This is because request (and any dialog function) is treated as a string, and we want a value. Also, in the first request, type"Request"Words",a,0. The zero will turn alpha-lock off in that box so...

If you just want a simple program... :Prompt a,b :Disp (a^2-b^2)^.5 Now, that is the most basic version, and not very good looking, but it will get the job done.

Another way to get around this is if you use "Auto" as your Exact/Approx mode and you want to see the approximate answer, hit the green diamond key and then enter instead of just enter. This will display the approximate answer.

The app "Graph 89 Free" on the play store will run a ROM of the TI-89 Titanium, which has built in units and unit conversions. The app is free, but the ROM must be acquired elsewhere. However, it it ILLEGAL to download the ROM or extract it from a TI-89 if you do not own it. If you own, go right...

First thing: unless you need the variables that aren't standard like x or y outside of the program, I would make them local. Otherwise you'll have a mess of variables if you keep using new ones. just do "Local x2,y2,..." for all of the non-standard variables. Second thing: your program is...

Hi there, I’ve come across a problem I can’t seem to solve. What I want to do is make a text box that with scrollable information. For example, when you do “One Var Stats” on the Stats and List Editor where it has all the information you scroll through and only the “Enter=OK” button. I’ve...

Hi all. I'm starting my college apps and started with MIT. Here's the prompt: "Tell us about the most significant challenge you've faced or something important that didn't go according to plan. How did you manage the situation?(*) (200-250 words)." Below is my response. What I want to know...

Travis_King, Sorry, I was thinking the question the whole time, but I guess I just forgot to type it. I'm wondering if this sounds like a good plan? Is it even worth taking both or just one or the other? Would it be too much work? From what I understand, Astronautical Engineering focuses on...

Hi all, I'm currently a junior in high school (going to be a senior in the 13-14 school year) and I'm starting to think about what I want to major in. i want to do Aerospace Engineering and eventually focus on Astronautical Engineering because it seems like a great way to apply all of the...

Homework Statement So, I'm building a "Monkey Gun" and I want to be able to find the instantaneous velocity of my dart at a certain time. I shoot the gun at some angle, θ. The problem is, if I divide the velocity into x and y components, each depends on and impacts the other (the force from...

Dick, That method will work perfectly! Sometimes the right answer is the one that seems too easy. Thank you for your help! cepheid, That's fine, it's an interesting idea, though. I'll have to play around with that after I finish this project! It shouldn't be too hard to do either, but I love...

Dick, I understand that I can aim the gun directly at the monkey because they will both fall at the same rate (in fact I did the calculations when I derived the equations and the whole system can essentially be treated as of there is no gravity). And yes, the only aiming is aiming the gun at...

cepheid, I didn't post to this category (my post got moved) so that's why I didn't follow the template. Good to know,though. No, the monkey isn't a stationary target. The monkey is suspended by an electromagnet powered by a battery. On the end of the barrel, there are two split wires that are...

"Monkey Gun/Shoot the Monkey" Equations Question Hi everybody! This is my first ever post, so if I mess something up that's why. So here's my question. For my physics final I chose to build a Monkey Gun (also known as Shoot the Monkey). I am completely done with the gun, tree, circuit...
