Could you please check if these are correct. I have done the working out on paper. Thanks.
Y0= -1
Y1= 0
Y2= -1
Y3= 0
Y4= -1
Y5= 0
Y6= 7
Y7= 0
Y8= 0
Y9= 2
Y10= -1
Y11= 0
Y12= -1
All other values of Y are 0.
$\displaystyle y[0] = -1 $
$\displaystyle y[1] = 0 $
$\displaystyle y[2] = -1 $
$\displaystyle y[3] = 0 $
$\displaystyle y[4] = -1 $
$\displaystyle y[5] = 0 $
$\displaystyle y[6] = 7 $
$\displaystyle y[7] = 0 $
$\displaystyle y[8] = -1 $
$\displaystyle y[9] = 0 $
$\displaystyle y[10] = -1 $
$\displaystyle y[11] = 0 $
$\displaystyle y[12] = -1 $
