Question

(+cot teta -cosec teta )( 1+ tan teta + sec teta)​

Answer 1

Answer:

2

Step-by-step explanation:

(1+cot theeta-csc theeta)(1+tan theeta+sec theeta)

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

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

(sin^2theeta + sin theeta×cos theeta + sin theeta + cos theeta×sin theeta + cos^2 theeta + cos theeta- sin theeta - cos theeta - 1 )/sin theeta×cos theeta

(1+2sin theeta×cos theeta- 1)/sin theeta ×cos theeta
