Isn't this what software is for?!?

Think Calc is hard...just wait for thermo. Nothing better than a take home test with one problem that takes 40hrs to complete.
It's even better when your professor's English is about as clear as mud. I will say it is all worth it in the end. A professional salaried job makes playing with cars and racing a little easier. Stick with it! |

Loki, how do you remember how to do that?
But pat, get one of those calculators that does everything. I had a voyage 200, but while they wouldn't let me use it in test it allowed me to double check all my answers for hw |

Hey Ben- When you used the product rule in step 3, Isn't the derivative of a constant Zero?
|
:ughug: loki you my math hero :love:

Thanks Ben, that helps. Then you can simplify 2(cos/sin)x to 2cotx. That's the final answer in my notes, so that must be how to get to it.
Thanks everybody for all the help. This is the best turbochaged miata/Calculus help Forum in the world!!! |
Right.
FWIW, I got help w/ that. There's a math major (grad w/ honors) in the kitchen. :gay: |

I've been thinking about doing that. I've always used my TI-83 that was given to me used 8 years ago:nono: Perhaps a higher level Texas Instruments? I've never heard of a Voyage before.

2 things about the voyage, full keyboard, and usb port to plug into a computer. TO download notes to it ;)

well i used to do the steps for each problem and then check it with the calc. I couldnt recommend it enough

Well, that's two good reasons right there:bigtu: Do any higer level calculators actually show the steps involved to solving the problem?

Problem: Y=ln(x^4(sin^2(x))) Find first derivative.
=(d/dx) ln(x^4(sin^2(x))) =4lnx+ 2lnsin^2x =(4/x)+2(1/sinx)cosx =(4/x)+2cotx ^^that is your answer I have the same book but I am in calc one, i hate differentiations *EDIT* sorry i didnt realize you already had the answer |
btw, ticalc.org
you can download programs that help find the answer... its a good reference, but we arent allowed calculators |
