`sin4theta cos 2theta = cos5theta sin theta`

If cos theta =4/5 then sin^2 theta cos theta + cos^2 theta sin theta is equal to :

Prove that : sin theta cos^3 theta - cos theta sin^3 theta = 1/4 sin4theta .

If cos theta=4/5 , then sin^2 theta cos theta+cos^2 theta sin theta is equal to : यदि cos theta=4/5 है,तो sin^2 theta cos theta+cos^2 theta sin theta का मान किसके बराबर होगा ?

If 5 cos theta -12 sin theta =0 , the value of (2 sin theta +cos theta )/(cos theta - sin theta ) यदि 5 cos theta -12 sin theta =0 , है, तो (2 sin theta +cos theta )/(cos theta - sin theta ) का मान ज्ञात करें |

Evaluate the following determinants: (b) |(cos theta, -sin theta),(sin theta, cos theta)| = cos theta (cos theta) - sin theta(-sin theta) = cos^(2) theta + sin^(2) theta = 1

Prove the following: "sin" theta+"sin" 3theta+"sin" 5theta+"sin" 7theta=4 cos theta cos 2theta sin 4theta .

Prove the following : sin theta+ sin 3 theta+ sin 5 theta+sin 7 theta=4 cos theta cos2 theta sin4 theta .

Simplify, costheta[[cos theta, sin theta],[-sin theta, cos theta]] + sin theta [[sin theta, -cos theta],[cos theta, sin theta]]

If 3 sin theta=2 cos theta , then 3 sin theta=2 cos theta , then (4 sin theta-cos theta)/(4 cos theta+sin theta) is equal to: यदि 3 sin theta=2 cos theta है, तो 3 sin theta=2 cos theta , then (4 sin theta-cos theta)/(4 cos theta+sin theta) का मान क्या होगा ?
