Hey again, I have a few more questions that the answer is not immediately clear to me.
Starting off: (note I'm still learning how to write in that math mode, so bear with me).
Steps showing how the answer is achieved will be greatly appreciated.
Edit: Another Question that's got me.
And another:
This style of question just gets me every time:
I've done this type before, but I didn't really get it then:
one more for the "need help" pile:
which i then turn into:alright, I'll stick with this Sharp one that I already have, borrow others sitting around at home and use my pc calculator when needed.
yeah, only problem is when I want to use it at school. It's not a huge problem, I'll prolly buy a Casio... which model do you recommend of the Casio brand?
I don't really know that much about it, when you say programmable, do you mean that you can change settings and modes (such as science mode, engineering modeetc) then yes.
If you mean programmable by the way you can add new functionality to it, then no.
But when it did the rounding error, I wasn't using the engineering mode.
also, it has a funky display style, google image it to see what I mean.
It is a Sharp EL-531WH
hmm, my calculator may have rounded. I'll try with my pc calculator.
yeah, I think my calculator had some roundoff error, which is annoying to say the least, as doing the same operation on pc, I got the correct answer: 1.3 nanovolts.
Hey, I'm just doing some Electronics homework and theres a couple of conversions that are confusing me a bit, and I am not sure whether I got the answer correct.
so what I have to do is convert the worded ammounts into something more appropriate, for example: 2000 Milli Amps = 2 Amps (getting rid of the unneccesary zeros).
Now onto my confusion:
300 Pico Volts + 1 Nano Volt. I got the answer 1nanovolt, which is somewhat confusing, did I do something wrong?
yes, yes it is.
Awesome, thanks.
Hmm yes, I think so, I'm not entirely sure how you combined it, specifically as to how you got the +7 on the LHS. But I think it has something to do with double negatives = positive.
Thanks for that, I can see how I can get the correct answer now.
Hey, so I've done this question a few times, and keep getting the same wrong answer, so I must be doing something wrong.
I don't really know how to write it yet on these forums, so I'll give you a drawing instead.
I'm in yr 11 in Australia. Doing Advanced Maths with Extension 1. For those of you not familiar with how we write Maths, then yeah, we put an s on the end.
For the past few years, I haven't really done any homework, so now it's really hard getting back into it, and jumping from general level maths to ADVANCED EXTENSION 1 is still quite tough for me.
So I'll prolly be here for a while, and once I am good enough at maths, I'll do my best to help out others.
I hope this forum is good, it seems pretty active.
