Question

(tan tetha/sec tetha-1) + (tan tetha/sec tetha+1)​

Answer 1

Answer:

2 cosec theta

Step-by-step explanation:

{tan theta ( sec theta +1) + tan theta (sec theta -1) } / sec²theta-1

or, 2 sec theta * tan theta / tan² theta

or, 2 sec theta / tan theta

or, 2 sec theta * cos theta / sin theta

so, 2 cosec theta
