The limit of cos2(x)/x as x approaches 0 does not exist. As x approaches 0 from the left, the limit is negative infinity. As x approaches 0 from the right, the limit is positive infinity. These two values would have to be equal for a limit to exist.
As X approaches infinity it approaches close as you like to 0. so, sin(-1/2)
Negative infinity squared is technically undefined in the real number system. In mathematics, infinity is not a number, it's a concept representing something unbounded. So squaring negative infinity doesn't really make sense in the traditional sense. But hey, if you want to get all philosophical about it, feel free to ponder the mysteries of the universe while you're at it.
probably x would be negative. This is because the square root of a negative number is not a real number (no real number squared can be negative). ory is 0. any number divided by 0 = infinity. and undefined is another way of saying infinity.
limit x tends to infinitive ((e^x)-1)/(x)

4x cubed y cubed z divided by x negative squared y negative 1 z sqaured = 4
The domain of y = 1/x2 is all numbers from -infinity to + infinity except zero. The range is all positive numbers from zero to +infinity, except +infinity.
Anything to the power of 1 is that same something, so infinity to the power of 1 is infinity. Keep in mind that infinity is a conceptual thing, often expressed as a limit as something approaches a boundary condition of the domain of a function. Without thinking of limits, infinity squared is still infinity, so the normal rules of math would seem to not apply.
The "value" of the function at x = 2 is (x+2)/(x-2) so the answer is plus or minus infinity depending on whether x approaches 2 from >2 or <2, respectively.

It is 1 over r squared, or r to the negative second power.
