Question

PLEASE HELP ME URGENT Check all that apply. tan(theta) is undefined for theta=

Answer 1

Answer:

Option A and B

Step-by-step explanation:

Option A : For $\frac{3\pi }{2}=\theta$

                    Tan θ = $tan(\frac{3\pi }{2})$

As we know tan (π + θ) = tanθ

So  $tan(\frac{3\pi }{2})$ = tan ($(\frac{\pi +\pi }{2})$

         =  $tan(\frac{\pi }{2})$

         = ∞ (not defined)

Option B :  For θ =  $(\frac{\pi }{2})$

                    tan θ = $tan(\frac{\pi }{2})$

                             = ∞ (not defined)

Option C :  For θ = 0

                  tan θ = tan 0

                           = 0

Option D : For θ = π

                  Tan θ = tan (π)

                             = tan (π-0)

                             = tan 0

                             = 0

Therefore, Option A and B are correct.

Answer 2

I'm pretty sure the answer is pi/2. Just plugged it in my calculator and it said error.

Yes it's A and B
