(1)/(sin^(-1))(2(x+y)(1-xy))/(x)

if y=(1)/(2)sin^(-1)((2xy)/(x^(2)+y^(2))) and y

Find the value of: tan((1)/(2)[(sin^(-1)(2x))/(1+x^(2))+(cos^(-1)(1-y^(2)))/(1+y^(2))]),|x| 0 and xy,|x| 0

Find the value of the following: tan((1)/(2))[sin^(-1)((2x)/(1+x^(2)))+cos^(-1)((1-y^(2))/(1+y^(2)))],|x| 0 and xy<1

If y=(1)/(2)sin^(-1)((2xy)/(x^(2)+y^(2))) and y lt x then Lt_(y to 0)=

Ify=(1)/(2)(sin^(-1)x),then(1-x^(2))y_(2)-xy_(2)=?

If y=(sin^(-1)x)^(2), then (1-x^(2))y_(2) is equal to xy_(1)+2(b)xy_(1)-2(c)xy_(1)+2(d) none of these

The solution of the differential equation xdy+ydx-sqrt(1-x^(2)y^(2))dx=0 is (A)sin^(-1)(xy)=C-x(B)xy=sin(x+c)(C)log(1-x^(2)y^(2))=x+c(D)y=x sin x+c

(xy)/(x-y)=(1)/(2);(xy)/(x+y)=(1)/(5) wherex +y!=0;x-y!=0

If y=(sin^(-1)x)/(sqrt(1-x^(2))), then ((1-x^(2))dy)/(dx) is equal to x+y (b) 1+xy1-xy(d)xy-2
