Question

`tanθ/(secθ + 1) = (secθ - 1)/tanθ`

Sum

Solution

डावी बाजू = `tanθ/(secθ + 1)`

= `tanθ/(secθ + 1) xx (secθ - 1)/(secθ - 1)` ..............[छेदाचे परिमेयकरण करून]

= `(tanθ(secθ - 1))/(sec^2θ - 1)`

= `(tanθ(secθ - 1))/(tan^2θ)` .....`[(∵ 1 + tan^2θ = sec^2θ), (∴ sec^2θ - 1 = tan^2θ)]` 

= `(secθ - 1)/(tanθ)` 

= उजवी बाजू

∴ `tanθ/(secθ + 1) = (secθ - 1)/tanθ`
