If -3x+12<0 then x varepsilon

For any x,y varepsilon R,xy>0 then the minimum value (2x)/(y^(3))+(x^(3)y)/(3)+(4y^(2))/(9x^(4)) equals

If sin theta - cos theta = 0, then what is the value of the expression (sin^6 theta + cos^6 theta) ? (A) 1 (B) (1/4) (C ) 3 (D) 4

If 5tan theta-4=0, then the value of (5sin theta-4cos theta)/(5sin theta+4cos theta) is (5)/(3)(b)(5)/(6)(c)0(d)(1)/(6)

Let theta, varphi varepsilon [0,2 pi] be such that 2cos theta (1-sin varphi) = sin ^ (2) theta ((tan theta) / (2) + (cot theta) / (2)) cos varphi -1, tan (2 pi-theta)> 0 and -1> sin theta <(sqrt (3)) / (2)

Let A=[[1,sin theta,1-sin theta,1,sin theta-1,-sin theta,1]],theta varepsilon((3 pi)/(4),(5 pi)/(4)) then |A| lies in (A),[(1)/(2),3)(B)[1,4)(C)[-1,2](D) none of these

If tan6 theta=(3)/(4) then (1)/(2)(3csc2 theta-4sec2 theta)=
