Please help me to find the separate equations of the line represented by following equations:
a) x^2+2(cosec a)xyy^2=0
b) x^2+2xy. tan ay^2=0

These two equations do not represent a (single) line. They are two different curves. For certain values of a, they overlap.

a) x^2y^2 = 0
represents the lines y = ±x
Ax^2+Bxy+Cy^2=0 represents the same lines rotated through an angle θ such that
cot2θ = CA/2B
so, we have cot2θ = 1/2 sin(a)
similarly for (b)
