" 2."(dy)/(dx)=cos(x+y)

If cos y = x cos (a + y) with cos a != +- 1 . Prove that (dy)/(dx)=cos^2(x+a)/sina

Solve the following differential equation x^(2)(dy)/(dx)-xy=1+cos((y)/(x)),x!=0

The solution of the differential equation x^2(dy)/(dx)-xy=1+cos""(y)/x is

The solution of the differential equation x^(2)(dy)/(dx)cos((1)/(x))-y sin((1)/(x))=-1, where y rarr-1 as x rarr oo is

The order of the differential equation (d^(2)y)/(dx^(3)) + 2 ((dy)/(dx))^(4) + (dy)/(dx) = cos x is

Solve (dy)/(dx)+2y=cos x.
