If the square
matrix has its inverse then it is……………matrix.
a) singular
b) nonsingular
c) zero
d) symmetric
A nonsingular matrix, also known as an invertible or non-singular matrix, is a square matrix that has an inverse. An inverse matrix, when multiplied by the original matrix, yields the identity matrix.
Other options mentioned:
a) Singular: A singular matrix is a square matrix that does not have an inverse.
c) Zero: A zero matrix is a matrix where all entries are zero. This option is not related to the presence of an inverse.
d) Symmetric: A symmetric matrix is a square matrix that is equal to its transpose. This option is not directly related to the presence of an inverse.
The ratio and
the root test fail when the limit of the ratio of n+1th and nth term of the
series becomes:
a) 0
b) 1
c) 2
d) both 1 and 2
The domain of the sequence is a set of………number.
a) irrational
b) rational
c) natural
d) negative
A point where derivative is …………is called the critical point.
a) does not exist
b) zero
c) both (a) and (b)
d) (a) or (b)
