Question

Complete the relation in ratio given.
$\frac{\sin \theta }{\cos \theta }=$_______.

Answer 1

$\begin{array}{c}\frac{\sin \theta }{\cos \theta }=.............\left[\begin{array}{c}\because \sin {90}^0-\theta =\cos \theta \\ \cos \left({90}^0-\theta \right)=\sin \theta \end{array}\right]\\ \Rightarrow \frac{\sin \theta }{\cos \theta }=\frac{\cos \left({90}^0-\theta \right)}{\sin \left({90}^0-\theta \right)}Ans.\end{array}$
