Answer 8

The domain, is all the possible independent variable values, in this case the x values that will result in an output y value

Answer 9

\[\cot(x) = \frac{ \cos(x) }{ \sin(x) }\]

Answer 10

When the sin(X) = 0, the cotangent function will be undefined

Answer 11

sin(x) = 0 for x = pi, 2pi,3pi,...,n*pi

Answer 12

so the cot(x) will be undefined at all values of x, where x is some multiple of pi.

Answer 13

therefore the domain of Cot(x) is, All x, such that x does not equal n*pi, where n=0,1,2,3....

Answer 14

so true

Answer 15

Ok thanks I was pretty sure it was true but i wanted to see if I was right

Answer 16

GRAPH of Y= SIN(x)
Y=SIN(x) = 0 , for X= multiples of pi
