The second inequality is related to the first.

Define,

a_1=x_2-x_1

a_2=x_3-x_2

b_1=y_2-y_1

b_2=y_3-y_2

Then,

a_1+a_2=x_3-x_1

b_1+b_2=y_3-y_1

If you substitute those values into this inequality is becomes exactly #1.

You can the result from #1 to show this one. - Apr 26th 2007, 07:15 PMmad_munky838
