Question

Given the value of $$ \sin \alpha  =\dfrac{3}{4} $$  , $$0< \alpha <\dfrac{\pi}{2}$$, find the value of $$ 	an \alpha $$  .

Uniteasy Admin · Accepted Answer

$$\because \sin \alpha =\dfrac{3}{4}    $$
$$\cos \alpha =\sqrt{1-(\dfrac{3}{4}  )^2}   $$
$$=\dfrac{\sqrt{7}  }{4}  $$
$$	an \alpha  =\dfrac{\sin \alpha  }{\cos \alpha  }  $$
=

$$ \dfrac{3}{\sqrt{7}  } $$
