Question

prove that LHS = RHS​

Answer 1

Answer:

1-cos/sin

(1-cos)(1+cos)/sin(1+cos)

1-cos²/sin(1+cos)

sin²/sin(1+cos)

sin/(1+cos)

Answer 2

Answer:

LHS=RHS

Step-by-step explanation:

• LHS=1+cos/sin.
• =(1+cos)(1-cos)/sin(1-cos)
• = 1-cos^2/sin(1-cos)
• = sin^2 / sin (1-cos)
• =sin/(1-cos).

RHS=Sin/(1-cos)

hence, RHS=LHS

hope you get it
