If `A=|(1,0,0), (12,sinx,cosx), (13,cosx,sinx)|,` then `|A|` is

intdx/sqrt (13+5cosx-12sinx)

intdx/sqrt (13+5cosx-12sinx)

The number of distinct real roots of |(sinx,cosx,cosx),(cosx,sinx,cosx),(cosx,cosx,sinx)|=0 in the interval -(pi)/(4)lexle(pi)/(4) is

If -pi/4lexlepi/4 then abs((sinx,cosx,cosx),(cosx,sinx,cosx),(cosx,cosx,sinx))=0 then find the number of solution

The number of distinct real roots of |(sinx,cosx,cosx),(cosx, sinx,cosx),(cosx,cosx,sinx)|=0 in the interval (-pi)/4lexlepi/4 is :

intdx/sqrt(13+5cosx-12sinx)

Solve (sinx)/(1+cosx)+(1+cosx)/(sinx)

If S={x epsilon [0,2pi]:|(0,cosx,-sinx),(sinx,0,cosx),(cosx,sinx,0)|=0} then sum_(xepsilonS)tan((pi)/3+x) is equal to

If sin2x=1 , then |(0,cosx,-sinx),(sinx,0,cosx),(cosx,sinx,0)| equals :
