(sina-cosa+1)/(sina+cosa-1)=2(1+cos eca)

The trigonometrical expression is sin² A + sin A - 2 cos A - 2 cos A × sin A = 0

Step-by-step explanation:

Given Trigonometrical function as :

= 2 (1 + cosec A)

Or, = 2 (1 + cosec A)

, Now, rationalizing

= 2 (1 + cosec A)

Or, = 2 ( 1 +

Or, = 2 (

Or, = 2 (

Or, = 2 (

Or, =  2 (

Or, = 2 (

Or, = 2 (

Or, = 2 (

Or, = 2 (

Or, sin A + sin² A = 2 cos A (1 + sin A)

Or,  sin A + sin² A = 2 cos A + 2 cos A × sin A

Or,   sin² A + sin A - 2 cos A - 2 cos A × sin A = 0

So,The trigonometrical expression is sin² A + sin A - 2 cos A - 2 cos A × sin A = 0     Answer

whats the
