" Q18.If "A=sin^(2)x+cos^(4)x," then for all real "x" : "

If A = "sin"^(2)x + cos^(4)x then for all realx :

If A = sin^2x + cos^4 x , then for all real x :

If A = sin^2x + cos^4 x , then for all real x :

If A = sin^2x + cos^4 x , then for all real x :

If A=sin^(2)x+cos^(4)x, then for all real x: (1) (3)/(4)<=A<=1(2)(13)/(16)<=A<=1(3)1<=A<=2(4)(3)/(4)<=A<=(13)/(16)

If A = sin^(2)x + cos^(4)x , where x in a real number

If a=(1)/(5cos x+12sin x) then for all real x
