I meant 4.3
May 26, 2018 18:53
The case is i print's 5 stars, but Log_2 20 gives me 3.32 which is 5
May 26, 2018 17:56
Log N goddamit ;)
May 26, 2018 17:56
Log

@Evil the case i s i'm not sure how I should do the calulation. But I would say n
May 26, 2018 15:45
Hi guys. I hope you can help me out here.

The loop for (int i = 0; i < n ; i*2) System.out.println("*");

Is the runningtime n^2, or is it log n?

Quick question, I know this graph is transitive but is it also reflexive? I'm not sure if it is enough that x -> y and y -> x when there also is an z.

I will take a look at it immediatley

Hi guys. I'm trying to learn how to do proof by induction and I just gave it a shot.
Could anybody of you confirm this is true or not (small example)

@LeakyNun
\[
f(x)
\left \{
\begin{tabular}{ccc}
1/x if x \neq 0 \\
0 if x = 0 \\
3 & 3 & -8
\end{tabular}
\right \}
\]

@LeakyNun sry but you lost mere there..... what do you mean by it isn't defined?
Oct 6, 2017 07:39
Good morning ;)
Do you guys know if f(x):=1/x is consideres a one to one, where x is a set of all real numbers.

Hi guys. I'm gonna try again, got disturbed in IRL before....

Do any of you know how to compare alternative forms of equations in maple?
No matter of what maple says false when I try to compare my two equations but I know they are the same!

f(x)=sqrt(3)/4-3/2*x^2+100x
g(x)=x*(100-3/2*x)+1/2*x*x*sin(60)
May 9, 2017 20:51
@TedShifrin times? And it doesn't help if i subsitute Sin(60) wit sqrt(4)/3 which is again the same

Hi guys. I'm trying to get Maple to evalute to expressions of an equation there is the same. I 've tried to use evalb((sqrt(3)/4-3/2)*x^2+100x=x*(100-3/2*x)+1/2*xxsin(60)) but the output is false for some reason however I know it is true which wolframalpha also states...... Do you know what I'm doing wrong here?

Thanks!

@SteamyRoot I have tried for almos an hour know -_- and no matter of what i Can't get it to work

Hi guys. Is there any mable expert here tonight?
I'm trying to subsitute some values into an equation, but for some odd reason it doesn't seem to wiork ?!
Feb 16, 2017 09:47
guys do you know if the cubic equation has a discriminant? my teacher states they don't I do......
Feb 16, 2017 08:19
i. i'm sure you guys know about the second degree polynomial, where f(0)=c and f'(0)=b there is showing us the tangentline in x=0 on the graph.

Do you know if there is anyting equal to the cubic polynomial?

@DMHO Honest anwser thoug ;) I just can't grasp that it isn't the right anwser.

Feb 14, 2017 18:48
I only need one root btw. and the root or the solution to the equation should be x=9.
Feb 14, 2017 18:46
Hi. I'm trying to turn this cubis equation ( x^3-9x^2+(1/2)x-(9/2)=0) into a depressed equation whit this formula(http://www.texpaste.com/n/vcqsur2h) for the depressed equation x^3+px+q
But for some odd reason the two equations doesn't have the same roots?

@Skillmon nice spotted!
Oct 30, 2017 19:07
Thanks guys! It sure does look alot cleanter in this way
Oct 30, 2017 18:18
Hi guys. How will you go around writing an equation like this
```
\begin{align*}
C(45,3) \times C(57,4) \times C(69,(12-(3+4)) \\
=\frac{45!}{(45-3)!3!} \times \frac{57!}{(57-4)!4!} \times \frac{69!}{(69-5)!5!} \\
= 6.29940220356447 \times 10^{16}
\end{align*}
```

It seems impossible to make this equation beautifull......
