A natural number is y is called perfect square if there exists an integer x such that y=x2
Not according to the usual definitions of "differentiable" and "continuous".Suppose that the function f is differentiable at the point x = a.Then f(a) is defined andlimit (h -> 0) [f(a+h) - f(a)]/h exists (has a finite value).If this limit exists, then it follows thatlimit (h -> 0) [f(a+h) - f(a)] exists and equals 0.Hence limit (h -> 0) f(a+h) exists and equals f(a).Therefore f is continuous at x = a.
csc(x) = 0 is the same as 1/sin(x) = 0. One over some other number is never equal to zero (though it is sometimes undefined). Therefore no x exists that satisfies that equation.
The only way I ever learned to find it was to think about it. The function f(x) = log(x) only exists of 'x' is positive. As 'x' gets smaller and smaller, the function asymptotically approaches the y-axis.
A nonconstant function is called periodic if there exists a number that you can add to (or subtract from) the argument and get the same result. The smallest such positive number is called the period. That is, nonconstant function f(x) is periodic, if and only if f(x) = f(x + h) for some real h. The smallest positive such h is the period. For example, the sine function has period 2*pi, and the function g(x) := [x] - x has period 1.
Using calculus to see if the function f(x) is continuous at a point (point c) involves three steps. These three conditions must be met: 1. f(c) exists, is defined 2. lim f(x) exists x-->c 3. f(c)= lim f(x) x-->c
DEFINITION: perfect squareA number p is called a perfect square if and only if there exists a whole number n for which p = n2 .So ask yourself if any whole number squared equals 250.15·15 = 22516·16 = 256nope
It is unknown whether an odd perfect number actually exists. If an odd perfect number exists it will be extremely large, that is in excess of 10300.
The answer is a scientific law hope that helps :)
No such number exists.

There exists a natural equilibrium. It maintains the creation and depletion of ozone.
Natural plasma exist only at very high temperatures, or low temperature vacuums.
