This was just on the calculus board, but that was 4 hours ago with 3 views. Now, its urgent.
Hallo to everyone!
Describe the behavior of f(x) to the left and right of each vertical asymptote.
f(x) = tan x/ sin x
Are (0, 8 ) and (0,-8 ) at least starting points?
The answer is the book says:
a= (4k + 1) pi/2
b= (4k+ 4) pi/2
I have no clue what they are talking about.
The only helpful thing in the book is the definition of a vertical asymptote:
The line x= a is a vertical asymptote of the graph of a function y= f(x) if either
lim as x--> a+ f(x) = +/- infinity
lim as x--> a- f(x) = +/- infinity
I'm really lost.
Does AP Calculus questions go on this board?
