If `f(x)=[(sinx,cosecx,tanx),(secx,xsinx,xtanx),(x^2-1,cosx,x^2+1)]` then `int_(-a) ^ a f(x) dx` equals

If f(x)=|(0,x^2-sinx,cosx-2),(sinx-x^2,0,1-2x),(2-cosx,2x-1,0)|, then int f(x) dx is equal to

f(x) = min{2 sinx, 1- cos x, 1} then int_0^(pi)f(x) dx is equal to

if f(x)=|[x,cosx,e^(x^2)],[sinx,x^2,secx],[tanx,1,2]| then the value of int_((-pi)/2)^(pi/2) f(x)dx is equal to

If f(x)=|(cosx, x,1),(2sinx,x^(2),2x),(tanx,x,1)| then Lt_(xto0)(f'(x))/x=

Given f(x) =|{:(0,x^(2)-sinx,cosx-2),(sinx-x^(2),0,1-2x),(2-cosx,2x-1,0):}| intf(x) dx is equal to
