Question

What is y = tan θ when θ = π?

Answer 1

Zero

Answer 2

Can you explain? :o I wanna find out how to do it.

Answer 3

Do you know what sin(pi) and cos(pi) equal? You have to understand those 2 things before tackling tan(pi)

Answer 4

I just know the value of it.

Answer 5

You know sin(pi) = 0 and cos(pi) = -1
tan(x) = sin(x) / cos(x)
So
tan (pi) = sin(pi) / cos(pi) = 0 / -1 = 0

Answer 6

ohhhhhhhhhhh, okay. Thanks so much!
