What’s the value of <br> tan (3arc cos 3/4)

Volgvan

<h2>Answer: -1.469</h2>

This trigonometric function can be written as:

$tan (3 cos^{-1} (\frac{3}{4}))$ (1)

Firstly, we have to solve the inner parenthesis:

$cos^{-1} (\frac{3}{4})= 41.409$ (2)

Substituting (2) in (1):

$tan (3(41.409))=tan(124.228)$ (4)

Finally we obtain the value:

$tan(124.228)=-1.469$
