    Finding the Angle Between a Vector in the yz-Plane and Another Vector

    I've done some remediations on it; it should be clearer now. Vector A= 3i + j - 2k Vector C = C2j + C3k I'm using the given information that this vector lies in the y-z plane. A.C = 0 = 3*0 + 1*C2 - 2*C3 C2 - 2.C3= 0 C2=2C3 C= 2C3j + C3.k Using the given magnitude of the...

    Finding the Angle Between a Vector in the yz-Plane and Another Vector

    I see now that I've had some misconceptions about the problem. I've tried to solve the problem but i am not sure about the result. Vector A = 3i + j - 2k and vector C is perpendicular to it and it is also lying on the yz plane. A.C = 0 = 3.Ci + 1.Cj -2.Ck Ci=0 since it is on they yz...

    Finding the Angle Between a Vector in the yz-Plane and Another Vector

    yeah, i guess i couldn't think of writing it in that way. they were just meant to be x, y and z's with hats. i'll probably be more thoughtful next time. HallsofIvy, I have found a result using dot product but what really bothered me with this question is not the solution but some things that i...

    I'm not capable of writing exactly as they are given, they are vectors.

    Finding the Angle Between a Vector in the yz-Plane and Another Vector

    Homework Statement Two vectors are given as A=3x+y-2z and B=x-z. A third vector C lying in the yz-plane is perpendicular to A and its magnitude is 7 units. Find the angle between C and B. Homework Equations cross and dot product The Attempt at a Solution I can't imagine of way, a...
