Sec theta + tan theta = 3 then fund cosec tgeta |
|
Answer» Tan theta =3-sec thetaTan=sin/cosSin/cos=3-sec thetaSin=(3-sec theta)cos theta After solving ,Sin=3cos theta - sec theta cos theta Sin=3cos theta -1/cos theta×cos thetaSin=3cos theta - 1 Cosec theta = 1/sin theta Cosec theta =1/3cos theta-1 Question is Sec theta +tan theta =3,then find cosec theta . |
