Question

if cosec thita- cott hita=2 then cosec thita equal to what

Answer 1

A/q
r= cosec theta - cot theta 
so, 1= 1(cosec theta -cot theta) 
=(cosec theta +cot theta) cosec^2 theta - cot^2 theta 
[ multiplying num. and denom. by (cosec theta +cot theta)] 
=cosec theta +cot theta (proved) 


as cosec theta= r +cot theta 
so, 1sin theta= r+ cot theta 
=>sin theta= 1(r+cot theta) 

and, cot theta= cosec theta- r 
=>tan theta= 1( cosec theta - r)
