A: If the transformed equation of a curve is 9X^(2) + 16Y^(2) = 144 when the axes are rotated through an angle 45^(@), then the original equation is 25x^(2) - 14xy+ 25y^(2) = 288. R: If f(x,y)=0 is the transformed equation of a curve when the axes are rotate through an angle theta then the original equation of the curve is f(x cos theta + y sin theta, -x sin theta + y cos theta)=0 |
