Cosec theta + cot theta =5/3Find sin theta

Answer»

Step-by-step explanation:

1/sin THETA + COS theta/sin theta=5/3

1+cos theta/sin theta=5/3

2cos^2 (theta/2)/2sin theta/2.cos theta/2=5/3

cos theta/2 / sin theta/2=5/3

cot theta/2=5/3

let theta/2 be x

cot x=5/3

means we GOT opposite and adjacent side LENGTH....so lets calculate the value of hypotenuse.

hyp=(5^2-3^2)^1/2

=4

therefore sin x =3/4....x=48.59

ie, sin theta/2 is 3/4....theta=97.18

therefore sin theta is approximately EQUAL to one

sin 97.18 approximately equal to one.
