If the axes are rotated through an angle of 45 0 in the anti clockwise direction then the equation of rectangular hyperbola x 2 – y 2 = a 2 changes to
Text Solution
Verified by ExpertsThe correct answer is:
D
x = Xcos45 0 – Ysin45 0 = 
y = Xsin45 0 + Ycos45 0 = 
∴ ∴ The transformed equation of x 2 – y 2 = a 2 is
⇒ ⇒ 2xy + a 2 = 0
