does 9.99999999 = 10? 

like if you think it is and dislike if you think it is not
does 9.99999999 = 10?

(sqrt(cos(x))*cos(999999999999999999999999999999999999999999999999999 x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5

Don't try solving it, just put it into google, it makes a nice heart!

idea from some other guy
thanks

When you've tried each combination of letters possible, so you decide to go through every number combination possible.

Usually when bored during work and or school
Guy 1 : instead of being productive, why not put in 999999999888888887777777666666555554444333221 into the google search bar?

Guy 2 : good idea, good idea.

Copy-paste it noobs.

Grrrrrrr you anger me....learn some maths! .9999 recurring IS equal to 1! Hell, I'll even prove it for you if you like -
We all know that 1/3 (a third) can be written decimally as 0.333333 recurring (i.e. the 3s go on forever). It is also obvious that by multiplying a third by three, we get three thirds (3/3) , which is equal to one.
-
If we look at this same process decimally, take the number 0.33333 recurring and multiply it by 3, and you will see that each 3 in the sequence gets turned into a 9. This gives us .99999 recurring, which, since it is the same as 3/3, is also equal to 1, as explained in the previous paragraph.
-
The reason for this is that as you add more 9s onto the number 0.9 (after the decimal point), it gets closer and closer to 1. Since there are an infinite number of 9s after the point in 0.99999 recurring, the difference between this number and 1 must be infinitely small, and therefore cannot be any greater than 0.
QED.
.999999999~ (recurring) is equal to one because it is .333333~ (1/3) multiplied by 3.
