1 Answer. Sorted by: 5. Yes, you are correctly using the standard way of computing the angle between two vectors, u⃗ through their inner product: θ = arccos(→u ⋅ →v ‖→u‖‖→v‖) Which given your vectors →u = [2, 2] and →v = [ − 1, 2], gives us: θ = arccos( 4 − 2 √22 + 22 ⋅ √( − 1)2 + 22) ≈ 71.57 ∘. Which ...Calculate the vector angle between two vectors using the dot product formula and the cosine rule. Enter the coordinates of the two vectors and get the result in degrees or radians, with steps and explanations. Show 8 more comments. 2. First you'll need to normalize the two vectors. Once that's done you can do. angle = arcos(v1•v2) where "angle" is the angle you want to find, "arcos" is the inverse of cosine function and the "•" is the dot product operator. Be careful, this will return only the relative and raw angle.The angle between the two vectors can be found using two different formulas that are dot product and cross product of vectors. However, most commonly, the formula used in finding the angle between vectors is the dot product.If we have two vectors, then the only unknown is #\theta# in the above equation, and thus we can solve for #\theta#, which is the angle between the two vectors.

The formula is: Atan2(y, x) So you can easily calculate the difference of the two angles relative to the x-axis: angle = -(atan2(y2, x2) - atan2(y1, x1)) If it's from first to finger tip, it's possible the finger vector is pointing back toward the wrist which could result in a 180 degree angle. If you take a dot product of the two finger vectors (Vector3.Dot (a, b)) and the result is negative, the vectors are pointing in opposite directions. – avariant.The angle between vectors is used when finding the scalar product and vector product. The scalar product is also called the dot product or the inner product. It's found by finding the component of one vector in the same direction as the other and then multiplying it by the magnitude of the other vector.The angle is 44.48384°, if you are measuring the angle around the origin (as you would expect, since "angle between two vectors"). Maybe you have your definition of which angle you wish to calculate envisioned incorrectly as I'm struggling to see how these two points could form the angle of 90°.After completing the last step, the calculator will measure the angle between two vectors, and the result will appear.
