Question

cos/1-sin = sec + tan​

Answer 1

Answer:

Step-by-step explanation:

We have,  

cos x /1 − sin x , = cos x /1 − sin x × 1 ,

= cos x /1 −sin x × 1 + sin x/ 1 + sin x ,

= cos x ( 1 + sin x ) /1 −$sin^{2}x$ ,

= cos x ( 1 + sin x ) $cos^{2}x$ ,

= 1 + sin x/cos x ,

= 1/ cos x + sin x/ cos x ,

= sec x + tan x
