Where am I getting wrong here?
In equations with higher power of variables, x and y, to find their tangent, on differentiating we get the slope in terms of the variables itself.
Now if we take one such restrains from conic sections, we know that all their tangents are linear in power. But then I get this:
y=(x/y)x +c
I get stuck in this step every time What should be done so as to find the c and return the equation back to linear ?
