Proving:

Step-by-step explanation:

$\ Given \ that:$

$\frac{1+sin \theta}{1-sin \theta} = ( ten \theta +sec \theta)^2$

$\ L.H.S$

$\frac{1+sin \theta}{1-sin \theta} \times \frac{1+sin \theta}{1+sin \theta}$

$\frac{(1+sin \theta)^2}{(1)^2-(sin)^2 \theta} \\\\\therefore sin^2 \theta = 1-cos^2 \ \theta \\\\\frac{(1+sin \theta)^2}{(1)^2-(1-cos^2 \ \theta)} \\\\\frac{(1+sin \theta)^2}{1-1+cos^2 \ \theta} \\\\\frac{(1+sin \theta)^2}{(cos \ \theta)^2} \\\\(\frac {1}{cos \theta }+\frac {sin \theta}{cos \theta} )^2\\\\(sec \ \theta + tan \ \theta)^2$

L.H.S=R.H.S
