Question

sec(theta) +tan(theta) - 1/tan(theta)-sec(theta)+1

Answer 1

Answer:

1.

Step-by-step explanation:

according to second identity

sec^2(theta)-tan^2(theta)=1

sec(theta)+tan(theta)= 1/sec(theta)-tan(theta)

sec(theta)+tan(theta)-1/tan(theta)-sec(theta)+1

1/sec(theta)-tan(theta)-1/tan(theta)-sec(theta)+1

0+1=1
