Answer:
Step-by-step explanation:
Cosa/1-sina+sina/1-cosa+1=sinacosa/(1-sina)(1-cosa)
LHS
Cosa/1-sina+sina/1-cosa+1
Cosa(1-cosa)+sina(1-sina)+(1-sina)(1-cosa)/
(1-sina)(1-cosa)
Cosa-cos^2 a+sina-sin^2a+1-cosa-sina+sina.cosa/(1-sina)(1-cosa)
-(sin^2a+cos^2a)+1+sina.cosa/(1-sina)(1-cosa)
-1+1+sina.cosa/(1-sina)(1-cosa)
sina.cosa/(1-sina)(1-cosa)
LHS=RHS
