Solve the equation: `(dy)/(dx)=(1-cosx)/(1+cosx)`

Find the general solution of each of the following differential equations: (dy)/(dx)=(1-cos x)/(1+cosx)

Solve: (dy)/(dx)+y=cosx

int(cosx)/(1+cosx)dx=

int(dx)/(cosx(1-cosx))=

Find (dy)/(dx) , when: y=(cosx)^(cosx)

intcosx/(1+cosx)dx

Find (dy)/(dx) when : y=(cosx)/(1+sinx)

If y=(sinx)/(1+(cosx)/(1+(sinx)/(1+(cosx)/(1+ ddotto oo)))) , prove that (dy)/(dx)=((1+y)cosx+ysinx)/(1+2y+cosx-sinx)

int(cosx)/(1-cosx)dx=
