A twitching eye can be one sign of stress, especially when it is related to vision problems such as eye strain (see below). Reducing the cause of the stress can help make the twitching stop. Tiredness: A lack of sleep, whether because of stress or some other reason, can trigger a twitching eyelid.
C(n,k) is the number of combinations you can make of k objects out of a given set of n objects. We see that C(n,0) and C(n,n) should be equal to 1, but they require that 0! be used. So 0! = 1 neatly fits what we expect C(n,0) and C(n,n) to be.(n,k) is the number of combinations you can make of k objects out of a given set of n objects.

1 - When Qx = 0 you have a discontinuity (Because you can't divide by zero). 2 - To find the points of discontinuity she simply sets the denominator equal to zero and solves for the variable. 3 - You also have a vertical asymptote at these points UNLESS the numerator is also equal to zero.4 - If both the numberator and the demoniator equal zero at the same time... for the same value of X... - When Qx = 0 you have a discontinuity (Because you can't divide by zero). 2 - To find the points of discontinuity she simply sets the denominator equal to zero and solves for the variable. 3 - You also have a vertical asymptote at these points UNLESS the numerator is also equal to zero.
