I know what you mean. When i was taught a certain way to do something I got used to doing it that way. However, later that year we had some kind of "tutoring" session to prepare for the TAKS test (state wide issued test in Texas) and that teacher kept telling me "No that is incorrect" when I...
Well, having that in Pre-calculus you cover trigonometric stuff I would say that both together is not really required but can help. I myself wouldn't have minded having trigonometry in my high school because I really love mathematics and like challenging myself. I took all the math courses...
The TI-89 has the weird symbol to let you know their are more than 1 solution. Take f(x)=cos(x) for example. If you input it into the 89 for where f(x) = 0 you should right away know that f(x) will cross 0 in more than 1 place. The 89 will give you something like (pi/2)(weird symbol). But...
Easiest solution in my opinion would be to just re-write it as (2x)^{-1/2} and simply take the derivative of that.
Don't forget it is f'(x)=n*(u)^{n-1} *u'
To be more precise for HallsofIvy the actual problem was as follows:
Determine whether the sequence converges or diverges. If it converges, find the limit.
the problem was a_{n} = (2^{1+3n}) ^{1/n}
There you go..that is the formula I was trying to remember but I just couldn't come to it so I tried to work it out a different way, which ended up being incorrect and the average joe's mistake.
Yes, I am well aware of this. I know when you get infinity to the power of zero the solution is not automatically 1 just because of the power, hence the reason it is an indeterminate form. The same goes with infinity divided by infinity or zero divided by zero. Right away one thinks..oh its...

I am trying to comprehend how you got the answer by finding the probability of students being in ONLY 1 class...the way I went about it was finding how many students were in each class ONLY which were Spanish-15, French-5, and German-0. From here add em' all up to get 20 students...
Well, I tried using L'Hopital's rule and I ended up getting 0 (zero) but then I tried njama's way and I got 1. And I remember back in HS my calc teacher mentioning something about this problem but I just can't seem to remember the details. I'll continue trying to determing this problem. I'm...
