BQ#5: Unit T Concepts 1-3

Sine and cosine will never have asymptotes because they will never be undefined. Since their ratios are y/r and x/r with r being 1, there will never be an undefined answer regardless if the value of x or y in the ratio.  However, tangent, csc, sec, and cot can be undefined which means they can have asymptotes based on their ratios: y/x, r/x, r/y, and x/y. If for example we were given tan with y=7 and x=0, we would get an undefined answer.
