Finding unit vector from two points
WebNov 10, 2024 · This is the unit vector that points in the same direction as \(\vecs ∇f(−2,3).\) To find the angle corresponding to this unit vector, we solve the equations \[\cos θ=\dfrac{−6\sqrt{61}}{61}\; \text{and}\; \sin θ=\dfrac{5\sqrt{61}}{61} \nonumber \] for \(θ\). Since cosine is negative and sine is positive, the angle must be in the second ... WebThere are two hints here as to the direction of the vector AB: 1) The arrow over the top of AB indicates that the vector starts at A and terminates at B; and 2) If you look at the diagram, it'll show that the arrow does, in fact, "point" toward the point B.
