Question

for what numbers x,-2π<=x<=2π,does the graph of y= cot x have vertical asymptotes?

Answer 1

cot x = cos x / sin x
so think if what value for x for sin x = 0 because cos x / 0 is undefined, that is where the asymtotes appear

Answer 2

don't for get there period of 2π,and i don't know or have graph of 2π.

Answer 3

So sin x = 0 when x = 0 , pi , 2pi and negative x value is just = -pi, -2pi

U really dont need a graph or anything for this

Answer 4

thanks
