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

(sin^2a+cos^2a)+(sin^2a+cos^2a)/coasina-1=1

1+(cos^2a+sin^2a-1=1

1-1+(sin^2a+cos^2a=1sin^2a+cos^2a=1.

Please add spaces to the equation to be proved because it is totally cut off. I can't tell what you need to prove. Also, please add parentheses where needed to make it clear which terms belong to each other.
