I tried solve this problem by considering this equation as a linear equation, and solve its homogeneous solution  x3y4z = 0 First we rearrange the equation of the surface into the form f(x,y,z)=0 x^22z^2 = y^2 x^2 y^2 2z^2 = 0 And so we have our function f(x,y,z) = x^2 y^2 2z^2 In order to find the normal at any particular point in vector space we use the Del, or gradient operator grad f(x,y,z) = (partial f)/(partial x) hat(i) (partial f)/(partial y) hat(j) (partial f)/(partial z Consider the initial value problem $$ y' \tan(x)\,y = \cos^2(x),\quad y(0) = C$$ For what values of C does the solution remain bounded for all values of x?
