`4(sin^(2)theta+cos theta)=5`

Prove that (sin^(4)theta-cos^(4)theta)/(sin^(2)theta-cos^(2)theta)=1

sin^(4)theta+cos^(4)theta=1-2sin^(2)theta cos^(2)theta

If sqrt3 cos theta =sin theta , then the value of (4sin^2 theta -5 cos theta )/(3 cos theta +1) is: यदि sqrt3 cos theta =sin theta , तो (4sin^2 theta -5 cos theta )/(3 cos theta +1) का मान ज्ञात करें

If (sin theta + cos theta)/(sin theta - cos theta) = (5)/(4) , the value of (tan^(2) theta + 1)/(tan^(2) theta - 1) is

(((cos theta+sin theta)^(4)-(cos theta-sin theta)^(4))/(sin theta cos theta))=?

A value of theta in (0, pi//3), for which |{:(1+"cos"^(2)theta, "sin"^(2)theta, 4"cos" 6 theta), ("cos"^(2)theta, 1+"sin"^(2)theta, 4"cos"6theta), ("cos"^(2)theta, "sin"^(2)theta, 1+4"cos"6theta):}| = 0, is

If sin theta+cos theta=a, then sin^(4)theta+cos^(4)theta=

If 4 - 2 sin^2 theta-5 cos theta=0, 0^@ यदि 4 - 2 sin^2 theta-5 cos theta=0, 0^@ < theta<90^@ है, तो sin theta+tan theta का मान क्या होगा ?

If 4-2 sin^2 theta-5cos theta=0, 0^@ यदि 4-2 sin^2 theta-5cos theta=0, 0^@< theta<90^@ , तो cos theta+tan theta का मान ज्ञात करें:
