BQ#5: Unit T-Concept 1-3

1. Asymptotes exist when the function is undefined, which means when you divide by zero. The ratios for the trig functions are: sine= y/r, cosine=x/y, cosecant=r/y, secant=r/x, tangent=y/x and cotangent=x/y. Sine and cosine do not have asymptotes because according to the ratios they will be always divided by 1 because r=1. The one creates restrictions for sine and cosine. If they are divided by 1 then they are not undefined. The other trig function can have zero as the denominator because they can be divided by zero since x and y 1 or zero.
