Prove that -4le5cos theta +3 cos (theta+pi/3)+3le10 for all values of theta

If A = 2(sin^6 theta+ cos^6 theta)- 3 (sin^4 theta+ cos^4 theta) then the value of 3 alpha such that cos alpha= sqrt((3+A)/(5+A)) is यदि A = 2(sin^6 theta+ cos^6 theta)- 3 (sin^4 theta+ cos^4 theta) है, तो 3 alpha का मान इस प्रकार ज्ञात कीजिए कि cos alpha= sqrt((3+A)/(5+A)) हो।

If 4 tan theta =3 , then find the value of (5 sin theta -3 cos theta )/(5 sin theta +3 cos theta ) . यदि 4 tan theta =3 , है, तो (5 sin theta -3 cos theta )/(5 sin theta +3 cos theta ) का मान क्या है?
