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:
Impossible to answer ! Infinity is a never ending quantity - and Pi is a never ending decimal !
Positive: (0, infinity)Nonnegative: [0, infinity)Negative: (-infinity, 0)Nonpositive (-infinity, 0]
I think you mean zero to negative infinity is {x: x< or equal to 0}
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.
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.
Negative infinity plus negative infinity equals negative infinity.
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
Infinity.
negative infinity
It Is
infinity. anything times infinity is infinity (with the exception of indeterminant forms like infinity/infinity)
No. Pi is a finite number.
Negative infinity plus one.
If you look at the graph of the tangent function, you will see it has a vertical asymptote at x = pi/2. This is because the tangent approaches infinity as t approaches pi/2. It approaches negative infinity as t approaches -pi/2.The distance between - pi/2 and pi/2 is pi which is the period.Another way to see this is tanx is sinx divided by cosx.We cannot have cosx equal to zero or we would be dividing by zero.So when does cosx=0? It happens when x=pi/2 or -pi/2. It also equal 0 asmultiples, both positive and negative ones, or pi/2 such as 3pi/2, 5pi/2 etc.
Negative pi is - 3.14.
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
Pi = 3.14 + infinity
