The function f'(x) = cos(ln x) is the first derivative of a twice differentiable function, f(x). on the interval 0

x =

Step-by-step explanation:

Data provided in the question:

f'(x) = cos(ln x)

For finding points of maxima or minima , put f'(x) = 0

therefore,

cos(ln x) = 0

or

cos(ln x) =

or

ln x =

or

x =

now to check for maxima or minima at x =

f"(x) =

thus

at x =

f"(x) =

=

=   < 0

hence maxima at x =

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.
