    Finding angle through cross and dot product

    My mistake. Its A= 2i+3j+k AxB=-5i-2j+16k abs(AxB) = 16.88 abs(AxB)=abs(A) x abs(B)sinθ ∴ abs(AxB)/(abs(A) x abs(B))= sinθ ∴ θ = 79.92 A.B=-3 A.B/(abs(A) x abs(B))= cos(theta) ∴θ = 100.08 The result of dot and cross product should be the same but its not in this case. Please help.

    Finding angle through cross and dot product

    By using both cross and dot products, the angle between 2 vectors can be found. But there is 1 question that I tried for countless times that the result of cross product and dot product are not the same. Here is the vectors that I am talking about A= 2i+3j=k B= -4i+2j-k The result by...
