Step 1
Multiply every element in the 1st1st column by its cofactor and add.
0|-2cos(x)-sin(x)cos(x)-2sin(x)3cos(x)+4sin(x)-4cos(x)+3sin(x)|+0|cos(x)sin(x)3cos(x)+4sin(x)-4cos(x)+3sin(x)|+0|cos(x)sin(x)-2cos(x)-sin(x)cos(x)-2sin(x)|0∣∣∣−2cos(x)−sin(x)cos(x)−2sin(x)3cos(x)+4sin(x)−4cos(x)+3sin(x)∣∣∣+0∣∣∣cos(x)sin(x)3cos(x)+4sin(x)−4cos(x)+3sin(x)∣∣∣+0∣∣∣cos(x)sin(x)−2cos(x)−sin(x)cos(x)−2sin(x)∣∣∣
Step 2
Умножим 00 на |-2cos(x)-sin(x)cos(x)-2sin(x)3cos(x)+4sin(x)-4cos(x)+3sin(x)|∣∣∣−2cos(x)−sin(x)cos(x)−2sin(x)3cos(x)+4sin(x)−4cos(x)+3sin(x)∣∣∣.
0+0|cos(x)sin(x)3cos(x)+4sin(x)-4cos(x)+3sin(x)|+0|cos(x)sin(x)-2cos(x)-sin(x)cos(x)-2sin(x)|0+0∣∣∣cos(x)sin(x)3cos(x)+4sin(x)−4cos(x)+3sin(x)∣∣∣+0∣∣∣cos(x)sin(x)−2cos(x)−sin(x)cos(x)−2sin(x)∣∣∣
Step 3
Умножим 00 на |cos(x)sin(x)3cos(x)+4sin(x)-4cos(x)+3sin(x)|∣∣∣cos(x)sin(x)3cos(x)+4sin(x)−4cos(x)+3sin(x)∣∣∣.
