TS EAMCET 9-Sep-2020 Shift 2 Solved Paper

By shifting the origin to the point (2,3) and then rotating the coordinate axes through an angle θ in counter clockwise direction, the
x=2+X‌cos‌θ−Y‌sin‌θ
and y=3+x‌sin‌θ+y‌cos‌θ, so the given equation is transformed to
(3+x‌sin‌θ+y‌cos‌θ)
and given as 4x2+2y2−1=0 and as xy is missing so
