Answer:
Determinant are special number that can only be defined for square matrices.
Step-by-step explanation:
Determinant are particularly important for analysis. The inverse of a matrix exist, if the determinant is not equal to zero.
How to find determinant
For a 2×2 matrix
For a 3×3 matrix
we first decompose it to 2×2
Example
Find the values of λ for which the determinant is zero
Equating the determinant to zero
s = * (1 ±5 )
s = 1.61 or -0.61
75%off.. she paid 4$ for the scarf. if 16 = 100% (divided by 4 is 25% ) 4×3= 12 which equals 75 %. im sorry for the lengthy explanation im sure there is an easier way to explain i hope u understand the point i was getting at. it is definitely 75% off though
Simplify
5 - 2i + 3 + 4i - (-6 + 2i)
Simplify brackets
5 - 2i + 3 + 4i + 6 - 2i
Collect like terms
(5 + 3 + 6) + (-2i + 4i - 2i)
Simplify
<u>= 14</u>
