Find angle between 3d vector and x axis
WebApr 7, 2024 · Find the angle using a calculator. Simply take the inverse sine of the cross product and magnitudes to find the angle between the vectors. Using your calculator, find the arcsin or sin-1 function. Then, enter in the cross product and magnitude. WebJan 23, 2024 · Calculate the cross product of your vectors v = a x b; v gives the axis of rotation. By computing the dot product, you can get the cosine of the angle you should rotate with cos (angle)=dot (a,b)/ (length (a)length (b)), and with acos you can uniquely determine the angle (@Archie thanks for pointing out my earlier mistake).
