sin^(2)y+cos xy=x

sin^(2)y + cos xy = k

Find (dy)/(dx) at x=1,y=(pi)/(4) if sin^(2)y+cos xy=k

Find the derivative of y w.r.t x in each of the following: sin^2y + cos xy = pi

If sin^(2)x+2cos y+xy=0 then (dy)/(dx)=

Find (dy)/(dx) at x=1 , y=pi/4 if sin^2 y+cos xy=k

cos (x + y), sin (x + y), - cos (x + y) sin (xy), cos (xy), sin (xy) sin2x, 0, sin2y] | = sin2 (x + y)

If 3sin(xy)+4cos(xy)=5, then (dy)/(dx)=(y)/(x) (b) (3sin(xy)+4cos(xy))/(3cos(xy)-4sin(xy))(c)(3cos(xy)+4sin(xy))/(4cos(xy)-3sin(xy))(d) none

lf_ (cos x + cos y-cos z = 0 = sin x + sin y + sin) then cos ((xy) / (2)) =
