Prove that (1-〖tan〗^2∅)/(1+〖tan〗^2∅)=(cos∅+sin∅)(cos∅-sin∅)

Prove that (1-〖tan〗^2∅)/(1+〖tan〗^2∅)=(cos∅+sin∅)(cos∅-sin∅)

in this video I am going to show you how to   Prove that  (1-〖tan〗^2∅)/(1+〖tan〗^2∅)=(cos∅+sin∅)(cos∅-sin∅) Posts on QUICK STAREsolve the question above. I also have related videos on proving in trigonometry, for more videos you can check on my youtube channel. stay tuned and watch till the end and don’t forget to subscribe.
