" 11."sin xy+cos(x+y)=1

Find (dy)/(dx) if,sin xy+cos(x+y)=1

Find (dy)/(dx) " if " sin x + cos y = xy "

If sin x + cos y = (1) / (3) and cos x + sin y = (3) / (4) then tan ((xy) / (2)) =

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

If f(x,y,z) = sin (xy) + cos(xz) , then f_("xx") is

If cos x+ cos y = 1//3 , sin x + sin y=1//4 " then " cos (x+y)=

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

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

(dy)/(dx)+(y)/(x)=(1+xy sin x)/(x cos x)

Draw the graph of following function y = cos ^ (- 1) (cos x) y = sin ^ (- 1) (sin x) y = cos (cos ^ (- 1) x) y = sin (sin ^ (- 1) x)
