\frac{tan \theta +sec \theta -1}{tan \theta - sec \theta +1}= \frac{1 + sin \theta}{cos \theta}<br /> <br />

    Kindly solve it covering all the steps ...

    A better idea is to show us what you have done and where you are stuck.


    Hint: Convert everything into a function of sines and cosines using

    \tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}}

    and

    \sec{\theta} = \frac{1}{\cos{\theta}}.

    I really hate having to repeat myself, but actually show us what you have done and where you are stuck...
