Step 1
Given: A=[3215]2×2,B=[0056]2×2
Step 2 AB=[3215][0056]
=[3×02×53×0+2×61×0+5×51×06×5]
=[0100+120+25030]=[10122530]
BA=[0056][3215]=[0×3+0×10×(2)+0×55×36×15×(1)6×5]
=[0+101561030]=[10940]

Let B be a 4x4 matrix to which we apply the following operations:
1. double column 1,
2. halve row 3,
3. add row 3 to row 1,
4. interchange columns 1 and 4,
5. subtract row 2 from each of the other rows,
6. replace column 4 by column 3,
7. delete column 1 (column dimension is reduced by 1).
(a) Write the result as a product of eight matrices.
(b) Write it again as a product of ABC (same B) of three matrices.

Can someone explain why I get wrong answer in simplifying this expression?
sin 11 π 12 sin 29 π 12 cos 13 π 12 cos 41 π 12
If we rewrite the expression with new angles,
29 π 12 5 π 12 and 13 π 12 11 π 12
we don't change the value of the expression. But, if we now use sine of sum of angles, we get 1 2 instead of 0.
Why does this happen? Do angles need to be in the same quadrant for the formula to work?
