    Urgent asymptote question??

    I have a math 12 final in about two hours and the only thing I can't seem to figure out is how to find the asymptote when you can't use a calculator to graph it? For example I've seen questions such as

    2. Which of the following is an asymptote of the graph of the function y = cotx

    5. Which of the following lines is an asymptote for the graph of y = sec x ?


    Does anyone know a rule to finding the asymptotes? What happens if there's a number in front of the x? Would that be too hard to figure out in your head?

    Vertical asymptotes are vertical lines located at values of x that make your function undefined.

    y = \cot x = \frac{\cos x}{\sin x} is undefned when \sin x = 0 ....

    y = \sec x = \frac{1}{\cos x} is undefined when \cos x = 0 ....
