Step-by-step explanation:
The envelope of a family of curves is a curve f(x,y,c)=0 whose equation is obtained by eliminating the parameter c from f(x,y,c)=0 and
∂c
∂f
=0, where
∂c
∂f
is the differential coefficient of f with respect to c, treating x and y as constants. Moreover, the envelope of the family of normals to a curve is known as the evolute of the curve. The envelope of the family of straight lines whose sum of intercepts on the axes is 4 is:
