Question

find tan 180

Answer 1

hint:
we can write this: \(\tan(180)=\sin(180)/\cos(180)=...?\)

Answer 2

You might want to draw the angle 180 deg. Can you then identify the "opposite side," the "adjacent side," and the "hypotenuse?"

Answer 3

sine/ cosine=tan

Answer 4

its 0

Answer 5

yup

Answer 6

that's right!

Answer 7

thanks everyone :3

Answer 8

are you using unit circle?

Answer 9

:)

Answer 10

I agree with Michele Laino's re-writing of tan 180, but would like to point out that

tan 180 = (opposite side) / (adjacent side).

Answer 11

Using the "unit circle" here is fine, but not essential.
