1. The problem statement, all variables and given/known data find the set of all points (x,y) which satisfy lxl + lyl = 1 2. Relevant equations 3. The attempt at a solution first i decided to make lxl and lyl into inequality. -1 < x < 1 -1 < y < 1 lxl = lyl - 1 so from any value of y between (-1,1) would work ? will this give lxl the correct result? will they both equal to 1 ? please help im confused.
