You've actually used a in 3 different ways! I can guess that the "a" inside the brackets should really be [itex]\lambda[/itex] but then what does "a= [-3,1] mean??teng125 said:Find the volume of the parallelepiped depending on λ with
a=[2a,2 ,2] b=[4,1,a] c=[2,2,a] where a=[-3,1]
the [-3,1] is it let says (x,y,z) represents x and z for my substitution to find volume??
since there is no variable in y??
What?? If lambda is a vector, why does it only have two components? And what could "the sign looks like summation" mean?teng125 said:it means lamda vector(the sign looks like summation)[-3;1]
