There is no number 'infinity' so we are obliged to ask for a limit:
lim pi-x as x tends to infinity. pi-x = 1/pix. As x increases pix increases 'much faster' making the fraction 1/pix smaller and smaller but always positive.
Thus when x is large the fraction will tend toward zero.
Incidentally, whenever you want to demonstrate these behaviours of functions for yourself may I suggest either of the following:
- GeoGebra which is free and can be installed on your own computer
- Wolfram-Alpha which is a web site that is free to use

What is infinity divided by pi?
Impossible to answer ! Infinity is a never ending quantity - and Pi is a never ending decimal !
How do you write in interval notation x is positive?
Positive: (0, infinity)Nonnegative: [0, infinity)Negative: (-infinity, 0)Nonpositive (-infinity, 0]
What is the set-builder notation of the problem the set of negative infinity and 0?
I think you mean zero to negative infinity is {x: x< or equal to 0}
Who discovered the last digits of pi?
The last digits of pi are unknown. The number is not a rational number and will continue on out to infinity. There was a satire written as a news story that appeared, but it was not true.
What does 1 divided by sin x look like?
1/sin(x) is also known as cosec(x). It looks a bit like a U, starting at "infinity" when x = 0, bottoming out at 1 when x = pi/2 radians and then returning to "infinity" at x = pi. Next, it is an upside down U, below the axis and peaking at -1: between x = pi and 2*pi. These U shapes alternate.
What is negative infinity plus negative infinity?
Negative infinity plus negative infinity equals negative infinity.
How do you take the integral from negative infinity to 4 of 1 over1 plus x2?
Recall that the antiderivative of 1/(1+x2) is arctan(x). arctan(negative infinity) = -pi/2. arctan(4) = approximately 1.325818. The answer then is arctan(4) - (pi/2) = approximately -0.244979
What is pi to the power of infinity?
Infinity.
What is negative infinity times positive infinity?
negative infinity
Is negative infinity plus negative infinity negative 7?
It Is
What is pi times infinity?
infinity. anything times infinity is infinity (with the exception of indeterminant forms like infinity/infinity)
Smallest negative number?
Point negative absolute infinity
Will pi calculate out too infinity?
No. Pi is a finite number.
What is the number before negative infinity?
Negative infinity plus one.
Why is March 14th 2009 Pi Day?
Pi = 3.14 + infinity
Is there such thing as negative infinity?
Yes and no. Technically, infinity cannot be negative because it is an idea, not a number, but negative infinity is used in several mathematical equasions
What is negative pi?
Negative pi is - 3.14.
