" |l.कद्दि "sin theta=(sqrt(3))/(2)," तब सिद्ध कीजिए कि "4cos^(3)theta-3cos theta=-1

cos theta - sqrt3 sin theta = 1

If sin theta=sqrt3/2 then prove that 4cos^3 theta-3cos theta=-1

If sin theta=(1)/(2), show that (3cos theta-4cos^(3)theta)=0

Taking theta=30^(@) , verify each of the following (i) sin 3theta=3sin theta -4sin^(3) theta (ii) cos3 theta=4cos^(3)theta-3cos theta

If sin theta - cos theta = (sqrt(3)-1)/(2), " then " theta equals

If sin theta+sqrt(3)cos theta>=1 then

If Sin theta + Cos theta = sqrt(3) Cos theta then 2 Cos theta - Sin 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।

(sin theta+cos theta)(1-sin theta cos theta)=sin^3 theta+cos^3 theta
