Vertical asymptotes are vertical lines near which the function f(x) becomes infinite. If the denominator of a rational function has more factors of (x - a) than the numerator, then the rational function will have a vertical asymptote at x = a.
Horizontal Asymptotes. A horizontal asymptote is a line y = c such that the values of f(x) get increasingly close to the number c as x gets large in either the positive or negative direction. Rational functions have horizontal asymptotes when the degree of the numerator is the same as the degree of the denominator.
Oblique Asymptotes An oblique asymptote is an asymptote of the form y = ax + b with a non-zero. Rational functions have oblique asymptotes if the degree of the numerator is one more than the degree of the denominator. The function g(x) above has an oblique asymptote, namely the line y = x. This is reflected in the last view of the graph of g(x) on a calculator.

since in quantum cryptography the care is taken only while distributing the key and the info is sent over an unsecure channel then by applying various key combinations we can decode the info as how we expect things to be decoded by the use of quantum computers. then how is quantum cryptography unconditionally secure when it is not computationally secure.

In an historical movie, two knights on horseback start from rest 74.3 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.264 m/s2, while Sir Alfred's has a magnitude of 0.300 m/s2. Relative to Sir George's starting point, where do the knights collide?

Why do atheists keep bothering themselves about God if they are so sure that god does not exist?

Are atheists indecisive people who cant even trust their own judgements? Or are atheists too wanting to believe in God ?

Yes i know that this question is not related to astronomy , but it somehow concerns all ,

For example, The first equation contains variables 'a' and 'b', Second 'a' and 'c', Third 'a' and 'd', and so on. So If i want to get an equation with 'a' and b,c,d,... (That means 'a' on x-axis and b,c,d,e,... on y-axis). Is there any software which can solve this problem?
