"Earthquake"  = "Scary"

Notice the pattern........

1/175  = 0.0057142857142857........

There is a repeated cycle of 6 digits.......

2 leading zeroes + 666 cycles of 6 digits = 3998 digits......so ......two more digits will give us 4000......and the second digit in the pattern is "7".....so.......this is the 4000th digit........!!!

I meant earthquake, by the way you spelled wrecking wrong.

(ʘᗩʘ'), we got an eartquake that was 5.3, and it made a crack in the freeway.

Thanks DragonLance, i didn't know that :)

When you are making a post there is a dropdown insert menu up the ribbons.

One of those is 'special characters'  You will find lots of useful characters in there :)

Just high winds at my house (40+ mph, at times).....but.....it WAS nerve-wracking.....!!!!

woah, how was the experience, SCARY. ┬┴┬┴┤(･_├┬┴┬┴

No problems here, it is all really good MG   

When you are trying to learn mathematics try not to care excessively about Latex.  Don't let it get in the way of your maths learning.   :)

Oh, if I write too much LaTex it does do that.

I cut some of my lines until it is working properly.  Then I 'ok' it.

Then I open a new Latex box and paste the cut code in there.  

So I may end up with 2 or 3 consecutive lots of LaTex coding.

It ususally only happens when the code is very long though :/

I might try looking for units that you can do elsewhere and then I can tie my teaching in with it.  It is VERY important that you get grounded properly in basic arithmetic.  Then you will be able to fly ahead.  :)

You got that right  !!!!.......one struck my city - Shreveport - two nights ago.......no damage to me.....[Thank Goodness ]

Oh, be safe cause there are tornados there.◕‿↼

Nope......I'm stuck here in Louisiana.........!!!!!

"Ronald"

Do you live in Nevada?

Me, too.......my waistline likes it, as well  !!!!!

I love mcdonalds ლ(´ڡ`ლ)

Really

Hilarious lmao XD

Ah....Mathcad......you did very well but you gave up a little too quickly, here........!!!!......notice the following factorization....

15sec^2(x)-32sec(x)+17=0

(15sec(x) - 17) (sec(x) -1)  = 0

So either......

sec(x) = 1  which happens at 0 and 360.....but, both of these are out of the requested interval....or....

sec(x)  = 17/15   which happens at about 28.072°  and about 331.928°

There aren't any numbers that add up to -4 and multiply to 24, so it can't be factored.

You could use the quadratic formula to solve for x, though.

Hold down the ALT key and type 251

ALT 251 for √

3x+y=1 and 5x-y=15

Using the first equation, y = 1 - 3x    ....and substituting this into the second, we have

5x - (1 - 3x) = 15

5x -1 + 3x = 15

8x - 1  = 15

8x = 16

x = 2     and y = (1 - 3x) = (1 - 3(2))  = (1 - 6)  = -5

So the solution point is (2, -5)

And the equation of the circle would be.....

(x - 2)^2 + (y + 5)^2  = 4

Yes there are a number of ways.

One is to simply use "^", which indicates exponents. Eg. x^2 = x²

Another is to use any of the three formula/calculation applications on the bottom-most header bar. (eg. LaTeX, Math Formula, Calculation). These all use "^" to indicate powers, though they will be formatted like this:

$${{\mathtt{x}}}^{{\mathtt{2}}} = {\mathtt{4}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = -{\mathtt{2}}\\
{\mathtt{x}} = {\mathtt{2}}\\
\end{array} \right\}$$....................$${{\mathtt{x}}}^{{\mathtt{2}}} = {\mathtt{4}}$$.............$$x^2=4$$

Lastly you can go to the insert tab, then go to symbols, and there you will find some limited exponents, as well as a number of other useful symbols.

1km=1,000 meters

5km=5,000 meters

1 hour=60 minutes=3,600 seconds

You know what to do next.
