Answer 1

Step-by-step explanation:

Hence our answer is proved

Answer 2

Answer:

Step-by-step explanation:

Hello there!!!

In the question that was posted it says

prove that  1-cos A/sin A= sin A/1+cos A

RHS: multiply and divide by sin A

we get sin A(1-cos A)/sin ^2A

expand sin^2A using formula

sin A(1-cos A)/1-cos^2A

sinA(1-cos A)/(1+cos A) (1-cos A)  

so we get

sin A/1+ cos A  LHS=RHS
