Question

(sin A +1-cos A)/(sin A -1+cos A)=(1+sin A)/cos A​

Answer 1

Answer:

Answer is here

Step-by-step explanation:

So by CROSS MULTIPLICATION we get

=sinacosa+cosa-cos^2a =sina-1+cosa+sin^2a-sina+sinacosa

After cancelling out the common terms we get

= -cos^2a=-1+sin^2a

By taking the -cosa there it becomes cos^2a and we can apply the property with sin^2a which is - (sin^2a+cos^2a=1)

Hence we get it as

=-1+1=0

Thus the answer is 0
