Question

Prove that : sinA/secA+tanA-1 + cosA/cosecA+cotA-1 =1

Answer 1

sec=1/sin cosec=1/cos cot=1/tan=cos/sin sina/1/sina+cosa/sina-1+cosa/1/cosa+cosa... 1. sin^2a+sina/cosa+cosa/sina-1+cos^2a+1=1 
(sin^2a+cos^2a)+(sin^2a+cos^2a)/coasin... 
1+(cos^2a+sin^2a-1=1 
1-1+(sin^2a+cos^2a=1sin^2a+cos^2a=1.
