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

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

If y=(x)/(x^(2)+1) , then find (dy)/(dx)

If y=f((2x-1)/(x^(2)+1)) and f^'(x)=sinx^(2) , then (dy)/(dx) is equal to

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

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

The differential equations of all circle touching the x-axis at orgin is (a) (y^(2)-x^(2))=2xy((dy)/(dx)) (b) (x^(2)-y^(2))(dy)/(dx)=2xy ( c ) (x^(2)-y^(2))=2xy((dy)/(dx)) (d) None of these

If y=1+x+(x^(2))/(2!)+(x^(2))/(3!)+……+(x^(n))/(n!) then (dy)/(dx) =…………

If x^(2)+y^(2)=t-(1)/(t)andx^(4)+y^(4)=t^(2)+(1)/(t^(2)), then ((dy)/(dx))_((1.1)) is…………

If 2^(x)+2^(y)=2^(x+y) then (dy)/(dx) is equal to

x^(2)(dy)/(dx) = x^(2) - 2y^(2) + xy
