Which of the following real valued functions is/are not even functions?
f(x) = x - [x], where [x] denotes the greatest integer less than or equal to x.
C.
D.
f(x) = x - [x], where [x] denotes the greatest integer less than or equal to x.
we know that,
if f(-x) = f(x), then function is even and if
f(- x) = - f(x), then function is odd.
So, f(x) is even.
So, f(x) is even.
So, f(x) is not even.
So, f(x) is not even.
Let p, q and r be the sides opposite to the angles P, Q and R, respectively in a PQR. If r2sin(P)sin(Q) = pq, then the triangle is
equilateral
acute angled but not equilateral
obtuse angled
right angled
