Let f(x) =`|{:(cos x ,1,0 ),(1,2cosx,1),(0,1,2cosx):}|` then

If f(x) =|{:(cosx,1,0),(1,2 cosx,1),(0,1,2 cosx):}|, "then" |overset(pi//2)underset(0)intf(x)dx| is equal to

If f(x) =|{:(cosx,1,0),(1,2 cosx,1),(0,1,2 cosx):}|, "then" |overset(pi//2)underset(0)intf(x)dx| is equal to

Let f(x)=|(2cosx,1,0),(1,2cosx,1),(0,1,2cosx)| then

If f(x)=|{:(cosx,1,0),(1,2cosx,1),(0,1,2cosx):}|" then "int_(0)^(pi//2)f(x)dx=

Select and write the correct answer from the given alternatives in each of the following:If f(x)=|(2cosx,1,0),(1,2cosx,1),(0,1,2cosx)| ,then f(pi/3) =

If f(x)=|(2cosx,1,0),(x-pi//2,2cosx,1),(0,1,2cosx)| then (df)/(dx) at x=(pi)/2 is

if f(x)=|[cosx,1,0],[1,2cosx,1],[0,1,2cosx]| then int_0^(pi/2) f(x)dx is equal to (A) 1/4 (B) -1/3 (C) 1/2 (D) 1

if f(x)=|[2cosx,1,0],[x-pi/2,2cosx,1],[0,1,2cosx]| then (df)/(dx) at x=pi/2 is
