Express $Cosec \theta$ in terms of $tan \theta$
Given :
The given term is $ cosec \theta$.
To do :
We have to express $Cosec \theta$ in terms of $tan \theta$.
Solution:
$Cosec θ$ in terms of $tan θ$.
We know that,
$cosec^2 θ - cot^2 θ = 1$ and $cot θ = \frac{1}{tan θ}$
Therefore,
$cosec^2 θ - cot^2 θ = 1$
$cosec^2 θ = 1+cot^2 θ$
$cosec^2 θ = 1+ \frac{1}{tan^2 θ}$
$cosec^2 θ = \frac{tan^2 θ+1}{tan^2 θ}$
$cosec θ = \sqrt{\frac{tan^2 θ+1}{tan^2 θ}}$.
therefore, $Cosec θ$ in terms of $tan θ$ is $\sqrt{\frac{tan^2 θ+1}{tan^2 θ}}$.
