That is correct. So what do you need help with?

#54 Re: Help Me ! » Distance » 2017-04-28 14:50:06

That is correct. Now one more...

What is the coordinates of this point?

Hi;

What is the address (coordinates) of that blue point?

#59 Re: Help Me ! » Distance » 2017-04-28 02:52:56

Seems you are still a bit confused about the address of points on a graph.

Hi;

Even when I substitute numbers for both m and T I still am unable to get a closed form.

The curve does look like a probability density function though.

Youtube is a great resource. I love the videos by the people, for the people.

Well, what could you do about that, people will be stupid anyway

Over here the two party system has been confusing the people since the beginning. Grandpappyd had the solution. One guy runs and the rest stand around him holding automatic weapons. Everyone votes for this fellow or else. Anybody says buh and they get decapitated. The only flaw I can see in his proposal...why do we need those guys standing around with the automatic weapons if we are decapitating?

Bob's banana story is making me hungry. Those b's look pretty good from here.

That fellow left out doing EM. But I am glad he did.

Hi;

Some of them act like they just discovered it yesterday. Not because they are lazy, but because it is a brand new idea... In Bumpkinland, it is taught first.

If (-2,3)=(x1,y1) so where is x2 and y2??

x2 = 0;

y2 = 3;

Hi;

How did this integral come to be? Research project? Contest problem? Book problem?

#75 Re: Help Me ! » Distance » 2017-04-26 14:49:33

There is no such thing as a negative distance.

The distance formula for points (x2,y2) and (x1,y1)

Because the number (x2 -x1) is squared and then added to (y2-y1)^2 it is easy to see that the distance is always positive.
