if sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=c prove that (dy)/(dx)=(y)/(x)

If sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=loga then (dy)/(dx) equals

If sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=k , k is a constant, then prove that (dy)/(dx)=(y)/(x) .

If sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=log a,then(dy)/(dx) is equal to (x)/(y)( b) (y)/(x^(2))(x^(2)-y^(2))/(x^(2)+y^(2)) (d) (y)/(x)

If sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=log a then (dy)/(dx) is equal to (x^(2)-y^(2))/(x^(2)+y^(2)) (b) (y)/(x) (c) (x)/(y) (d) none of these

If sin^(-1)((x^(2)-y^(2))/(x^(2)+y^(2)))=log a then (dy)/(dx) is equal to (x^(2)-y^(2))/(x^(2)+y^(2)) (b) (y)/(x) (c) (x)/(y) (d) none of these

If sin theta=sqrt((x^(2)-y^(2))/(x^(2)+y^(2))) then the value of sqrt(sec^(2)theta+tan^(2)theta)

Evaluate : underset(xrarry)"lim"(sin^(2)x-sin^(2)y)/(x^(2)-y^(2))

sin ^ (- 1) (x ^ (2) -y ^ (2)) / (x ^ (2) + y ^ (2)) = k then
