Best ResponseYou've already chosen the best response.0what do you mean? that's exactly what I am asking. I mean what the symbol in the calculator?

Best ResponseYou've already chosen the best response.0There is no f symbol in the calculator :D

Best ResponseYou've already chosen the best response.0then how do we calculate it? everyone in my class was doing so. :/

Best ResponseYou've already chosen the best response.0Maybe is that in hexadecimal? need to switch calculator to hex mode

Best ResponseYou've already chosen the best response.0I have a fx991MS calculator. There's no such mode.

Best ResponseYou've already chosen the best response.0Then that will make it harder.....especially with the 1.5. Can't even find a calculator that will do heximal? points... could convert from hex back to decimal the f is easy that is a 15 one is just one...but fractions I don't see much on the web on fractions but it might mean .8??? so in decimal maybe and I do mean maybe it means 15 * 1.8 = 27 convert back to hex and get 1B???? But that is pretty sketchy. I tried 2 calculators here at home and neither of them will do fractional hex. And if your class is doing hex/octa/binary conversions a calculator with those modes is gonna be kind of important.

Best ResponseYou've already chosen the best response.0hmm I don't know why you're taking the hexadecimal? I don't think its relevant. I think you didn't understand my question. I need to find the function of (1.5). That's it. I am pretty sure most of the students the sa,e calculator as mine. So there's another way out I suppose.

Best ResponseYou've already chosen the best response.0except f(1.5) is not a function. It is part of a function but there has to be more after the f(x) part

Best ResponseYou've already chosen the best response.0Well the question is: \[f(x)=x1/x ^{2}+1\]

Best ResponseYou've already chosen the best response.0So in order to find f(x) we input x= 1.5,1.1,1.01,1.001 etc etc.

Best ResponseYou've already chosen the best response.0hehe ok then to solve the function for f(1.5) replace each of the x's with 1.5 (1.5)1/(1.5)^2 +1 .....

Best ResponseYou've already chosen the best response.0that looks like you are using a table to find a limit?

Best ResponseYou've already chosen the best response.0LOL Ohhh okayyyy. Yeah I guess so. Our prof. called it the calculator method lol

Best ResponseYou've already chosen the best response.0so ya just enter the different values into the equation wherever there is an x. I'll do a simpler function x+2 but in the values for x and write down the answer 1.5 + 2 =3.5 1.1 + 2 =3.1 1.01 + 2 =3.01 and you will see the answers get closer and closer to some value in this case 3 so the limit as x > 1 f(x)=x+2 is 3

Best ResponseYou've already chosen the best response.0and one last thing if you are still looking at this you will have three parts to this function the limit that x is approaching, the f(x) part and then the equation part

Best ResponseYou've already chosen the best response.0hey if you're there, do you know what we will do if lim x approaches to \[\Pi\]
