cos^(-1)((dy)/(dx))=x+y

Solve: (i) sin^(-1)((dy)/(dx))=x+y (ii) (dy)/(dx)=cos(x+y) (iii) (dy)/(dx)=(4x+y+1)^2

(dy)/(dx)=cos(x+y)

(dy)/(dx)=cos(x-y)

if y=cos^(-1)((1-x)/(1+x)) then find (dy)/(dx)

If y=| a^(2) a 1 (cos x)/(cos n)(x+1) cos n(x-1)+c (dy)/(dx)=

If y= cos^(-1)((2x)/(1+x^(2))) , then (dy)/(dx) is -

If y=| a^(2) a 1 (cos x)/(cos n)(x+1) cos n(x+1)+c (dy)/(dx)=

Solve the differential equation: (i) (1+y^(2))+(x-e^( tan ^(-1)y))(dy)/(dx)=0 (ii) x(dy)/(dx)+cos^(2)y=tan y(dy)/(dx)

If y= y(x) ( 2 _ cos x ) /( y+1) (( dy )/(dx)) =- sin x, y (0) =1 then y((pi)/(2)) equal ____.
