If cos A = √ 3 2 , then tan 3A = Options: A . &nbsp 0 B . &nbsp 1 2 C . &nbsp 1 D . &nbsp ∞

Answer: Option D : D We have cos A = √ 3 2 ⇒ A = 30 ∘ ⇒ tan 3A = t a n 90 ∘ = ∞ .

If cos A = √32, then tan 3A =

Question -

If cos A =
$\frac{\sqrt{3}}{2}$ , then tan 3A =

Options:

A . 0

B .

\frac{1}{2}

C . 1

D .

\infty

Answer: Option D
:
D

We have cos A =
$\frac{\sqrt{3}}{2}$ $\Rightarrow$ A = $30^{\circ}$

$\Rightarrow$ tan 3A = $t a n 90^{\circ}$ = $\infty$ .
