Let a,b,c be three vectors such that a ne 0 and a xx b = 2a xx c,|a| = |c| = 1, |b| = 4 and |b xx c| = sqrt(15) . If b - 2 c = lambda a, then lambda is equal ot
If A is a square matrix such that |A| ne 0 and m, n (ne 0) are scalars such that A^(2)+mA+nI=0 , then A^(-1)=
If A is a 2 xx 2 matrix such that |A| ne 0 " and " |A| = 5, write the value of |4A|.
If the elements of a 2 xx 2 matrix A are given as a _(i,j) = {{:(1",", i ne j),(0"," ,i = j ):}, then the matrix A is :
If f(x) + f(y) = f((x+y)/(1-xy)) for all x, y in R (xy ne 1) and lim_(x rarr 0) (f(x))/(x) = 2 , then
