Find the equation of the circle x2 + y2 = 1 in terms of x' y' coordinates, assuming that the xy coordinate system results from a scaling of 3 units in the x’ direction and 4 units in the y' direction.
1
3(x')2 + 4(y)2 = 1
2
\({\left( {\frac{{x'}}{3}} \right)^2} + {\left( {\frac{{y'}}{4}} \right)^2} = 1\)
3
(3x')2 + (4y')2 = 1
4
\(\frac{1}{3}(x')^2+\frac{1}{4}(y')^2 = 1\)
