If `y=2^(3^(x))`, then `y'` equals

if x+y=(2 pi)/(3) and cos x+cos y=(sqrt(3))/(2) then x,y is equal to:

Let y = y (x) be the solution of the differential equation ( x - x ^(3)) dy = ( y + y x^(2) - 3x^(4)) dx , x gt 2 . If y (3) = 3 then y (4) is equal to :

If x+y+z=0 , then x^3+y^3+8 equals

If x^(2)+y^(2)=1 and P=(3x-4x^(3))^(2)+(3y-4y^(3))^(2) then P is equal to

If f(2x+3y,2x-7y)=20x, then f(x,y) equals

If f(2x+3y,2x-7y)=20x, then f(x,y) equals:

If y=cos2xcos3x , then y_(n) is equal to

If log_(5)(3^(x)-4^(y))=3 and 3^((x)/(2))-2^(y)=5, then (x)/(y) is equal to
