Question

When angle of rotation of axes is tan-12 the
transformed equation of 4xy – 3x2 = a’ is
(A) 2xy + a² = 0
(B) XY - a² = 0
(C) x2 – 4y2 = a2
(D) x2 – 2y2 = a2​

Answer 1

Answer:

When angle of rotation of axes is tan-12 the

transformed equation of 4xy – 3x2 = a’ is

(A) 2xy + a² = 0

(B) XY - a² = 0

(C) x2 – 4y2 = a2

Step-by-step explanation:

When angle of rotation of axes is tan-12 the

transformed equation of 4xy – 3x2 = a’ is

(A) 2xy + a² = 0

(B) XY - a² = 0

(C) x2 – 4y2 = a2

(D) x2 – 2y2 = a2
