I hate calculus..... lol but thanks for you help man

9e^(9x)-e^(-x)=0 Becomes 9e^(9x)=e^(-x) ln(9e^(9x))=ln(e^(-x) 9*9x=-x 81x=-x 81x+x=0 x(81+1)=0 x=0 ??? I must be doing something wrong still.

That was my first thought, but then you are taking the natural log of 0, which is not possible. :( I tried that, but only gives a decimal value, just like WolframAlpha... which I believe is useless in this situation. Come on Calc Professors, where you at?! lol

Ok, I give up. I need to find where the function is increasing and decreasing. The function is... f(x)=e^(9x)+e^(-x) .... f'(x)=9e^(9x)-e^(-x) My problem is solving for where the function equals zero. Any help would be greatly appreciated. Also here is another problem I'm having the same...

I am stuck on this problem and am not going anywhere. My attempted answer is shown in the box. http://imageshack.us/photo/my-images/197/screenshot20121008at648.png/

Thank you mark, I think I fixed the things you have mentioned. String userString = scan.next(); boolean value = true; for(int i=0;i<userString.length();) { if(userString.charAt(i)!='0' || userString.charAt(i)!='1') { value = false; if (value == false) {break;} i++; }...

Ok, I think I'm getting somewhere. String userString = scan.next(); boolean value = true; for(int i=0;i<=userString.length();) { if(userString.charAt(i)!='0' || userString.charAt(i)!='1') { value = false; i++; } Still confused on the next step. Not sure how I am going to declare that the whole...

My professor gave me this problem due tomorrow. I am having a hard time trying to figure it out. I know he wants us to figure out if it is a binary number and then switch it to a decimal value. I just can't figure out what I'm doing wrong. My code below, I am on step 2b) //Part 2...

I cannot decide what to do. I am currently testing out the 13" i5 Macbook Air for the first time. I love the build quality, speed of the SSD, and smoothness of the Mac Os. But, for the same price I could buy a decent gaming laptop. Price($1000-1500) The problem I am having is finding a...

Yeah, but what do expect from a person who it's their first time programming and have only had a month of lessons from a professor who barely speaks English. lol Edit: Run on sentence much? I think so.

Thanks you good sir. I think I got it. public class JavaHomework1pt2 { public static void main( String [] args ) { int number =24362; System.out.println("First digit = " + ((number)/(10000)) % 10); System.out.println("Second digit = " +...

I need to pull out single digits out of a number ex. For number 24362 The output should be: I do not understand how to do this. My instructor told me to use "/ and %" but the only one I know that is right is my fifth digit below. package javahomework; public class...

Hm, I tried multiple links and nothing is working. On the dv6 model they integrated the up and down arrows basically on one key. As a beginner programmer, I do not know if I will be using those keys that much.

Laptop being considered I've been looking at the HP dv6 for a while, but one thing I am worried about is the keyboard. The arrow keys are very strange, and the keyboard is set up different. My question is would you still get it? I get 10% off at Walmart and I have a $50 gift card so I'm...

haha yes I caught myself in a few mistakes, but you verified my corrections to be right. As far as my name and city I'm not too worried about, but thanks for the advice. Thanks for your help though man. Edit:Just verified with the professor and he says everything looks good! :D
