or rather, his calculator (I wanted to put that all in subject but it wouldn't let me.)
A year ago I could have been like all my peers and gotten a Ti 83 but (As I want to be an engineer and also I'm super nerd) I went with the HP 49G instead. So far I've been able to get along just fine. This was in part due to the fact that my teacher last year rarely used a calculator period.
Anyway I'm having a few troubles now figuring out the "HP Equivalent" of a few Ti things and wondered if you guys could help me. I've been looking up and down Google but hopefully somebody else will come up with better search terms or just knows this stuff.
We're graphic quadratic forumulas. I don't know what the proper name is to be honest but it's basically where you get 2 or 3 sqiggely lines stuck together a'la roller coaster.
Problem 1: Once you've graphed on the Ti you can hit {Calc} {Value} to which the calculator prompts "X=" you give it an X and it gives you a Y and jumps to that spot on the graph. I can trace my line but sometimes it does things like jump from (1.988 , 0.234) to (2.033 , 0.132) and what I really need is (2, Y). I realize I could just plug in 2 for x and solve the equation but if the Ti can automate this than the HP ought to be able to.
Problem 2: Minimum and Maximum. The Ti has another button that will tell you how high and how low the function goes on the graph. HP equivalent??
We've touched on how to do this stuff by hand, but the reality is that now days Math is taught using Calculators and if you can't drive your calculator you can get stuck in the dust. My sister has a Ti I could borrow but I've found just from borrowing other classmates calculators that my brain is stuck in RPN mode and I have a really hard time thinking Algebraically /ubbthreads/images/graemlins/wink.gif
