8 -4 -3
3 -9 -5-8 8 8
This is a matrix of 3 rows and 3 columns (it's called square matrix because the number of rows = the number of columns)
To localise an element of a matrix we use indices R and C, the first index being ALWAYS the row and the second, ALWAYS the column.
Hence:
A₂₃ = the element in row 2 and column 3, that is - 5
COLUMN
1st 2nd 3rd
--------------------------------
1st | 8 -4 -3
ROW 2nd | 3 -9 -5 3rd |-8 8 8
Answer: 1/3
Step-by-step explanation:
First right it out:
8/24
Then see what number can go in each number:
8 can go in 8 itself and also it can go in 24
Then divide:
8/8 = 1
24/8 = 3
Then you get your answer:
1/3!!!!
Use double angle identity
We can relate '6x' to '3x' in the same way since 6 is 2*3.
Now sub into left side of identity. Simplify until it equals right side.
