(sec^(2)y)/(dx)+(dy)/(dx)+x*" tomy "=x^(3)

sec ^ (2) y (dy) / (dx) + x tan y = x ^ (3)

The differential equation sec^(2) y (dy)/(dx) + ytanx =x^(3) is

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

If y=x log((x)/(a+bx)), thenx ^(3)(d^(2)y)/(dx^(2))= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^(2)y(dy)/(dx)-x(d)(y(dy)/(dx)-x)^(2)

(dy)/(dx)+y tan x=sec x

(dy)/(dx)+y sec x=tan x

If y=xlog(x/(a+b x)),t h e nx^3(d^2y)/(dx^2)= (a) (x(dy)/(dx)-y) ^2 (b) x (dy/dx)-y (c) y(dy/dx)-x (d) (y(dy/dx)-x)^2
