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.- cxiangzhi

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...- cxiangzhi
