lightning good thinking but he had a random name which he linked to foruminfinity.com(doesn't exist).
MIF i did look through a lot of his posts and i think he also bypassed your "swearing filter".
he only had 2 different messages repeating throughout the forum so it was a bot.
lightning to notify MIF Go to mathisfun.com and click contact us.Then u can send him a message.
simron check ur messages!

isn't that the same as saying sin/cos/tan ^-1?
post #7?

lightning
i guess it was shut because MIF was cleaning up the mess.
it was a new member called foruminf2. the best thing you could do is notify MIF if there is a spammer.
MIF i hope he doesn't come back(or anyone else like him!). Did you notify PunBB about it or is it your programming fault?
How did you block him from accessing site? IP ban?

#313 Re: Help Me ! » distance between parallel lines » 2009-01-04 16:42:24
first graph y=2/3x-4
if a line is perpendicular to y=2/3x-4
its slope is the negative reciprocal of the slope of the line y=2/3x-4
negative reciprocal of 2/3 = -3/2
now you know the slope of the perpendicular line
so u get y=-3/2x + b
to solve for b plug in the point (-1,-1)
-1 = -3/2(-1) + b
-5/2=b
perpendicular line : y= -3/2x - 5/2
to solve for x in (x,2) plug it in the perpendicular line equation
2 = -3/2x -5/2
7/2 = -3/2x
-7/3 = x
to graph an equation
y = 2/3x -4
your first point would be (0,-4) because your y-intercept is -4.
then using your slope you either go up 2 and right 3 or down 2 and left 3 to give you (3,-2) and (-3,-6) respectively.

£2/week + 2% gives £2.02/week
That sounds wrong to me....
£2 * 2% = 0.04
£2/week + 2% gives £2.04/week

2.What csc/cot/sec are?
3. How do they help me with triangles?
4. any other things related to them.
Thx for your help,

Nice application, easy to use!:D
How do i change value when it is a pie chart? I can change values right on the graph when it is line/bar/table but not in pie.

i feel like these were 2 easy for me ganesh. I like patterns and like to solve them, if you have more pls post.

I agree nice 100 Tigeree!
Thanks to ganesh and you we have reached 100!
Now lets start of with some Hair and Nails shall we:
101.Facial hair grows faster than any other hair on the body. If youve ever had a covering of stubble on your face as youre clocking out at 5 oclock youre probably pretty familiar with this. In fact, if the average man never shaved his beard it would grow to over 30 feet during his lifetime, longer than a killer whale.
102. Every day the average person loses 60-100 strands of hair. Unless youre already bald, chances are good that youre shedding pretty heavily on a daily basis. Your hair loss will vary in accordance with the season, pregnancy, illness, diet and age.
103. Womens hair is about half the diameter of mens hair. While it might sound strange, it shouldnt come as too much of a surprise that mens hair should be coarser than that of women. Hair diameter also varies on average between races, making hair plugs on some men look especially obvious.
104. One human hair can support 3.5 ounces. Thats about the weight of two full size candy bars, and with hundreds of thousands of hairs on the human head, makes the tale of Rapunzel much more plausible.
105. The fastest growing nail is on the middle finger. And the nail on the middle finger of your dominant hand will grow the fastest of all. Why is not entirely known, but nail growth is related to the length of the finger, with the longest fingers growing nails the fastest and shortest the slowest.
