Question

5sin theta - 12cos theta =0 then what is the value of cosec theta

Answer 1

Answer:

5sin theta - 12cos theta =0

divide both sides by sin theta

we get

5 - 12cot theta = 0

12 cot theta = 5

cot theta = 5/12

cot²theta = 25/144

we know

cosec²theta = 1 + cot²theta

cosec²theta =1+25/144

cosec²theta = 169/144

cosec theta = 13/12
