Bonus Problems I: Transformations of curves

Complete the parts (a){(d)

Determine if there exists a linear transformation T : R2 ! R2 that transforms a curve

on the left into a curve on the right. If yes, nd the standard matrix of an appropriate

transformation. If no, explain why.

(a) Circle x2 + y2 = 1 ! ellipse x2 ô€€€ 4xy + 5y2 = 1

For example, the standard matrix of such a T is

No, there is no such transformation, because
