Question

If 3 cos theta =3then find the value of cosec theta

Answer 1

Answer:

3 Cos theta =3

therefore cos theta =3/3=1

now sin square theta + cos square theta=1

sin square theta = 1 - cos square theta

sin square theta= 1-1=0

sin theta =0

therefore theta=30 deg

sin 30=1/2

therefore cosec 30=2
