Is the physical quadrilateral rule and the triangular rule the same? Is the principle of parallelogram and triangle physically identical? Is the principle of parallelogram and triangle physically the same?

It's the same thing.

What is the difference between vector triangle rule and parallelogram rule? What is the difference between the vector triangle rule and the parallelogram rule? What is the difference between vector triangle law and parallelogram law?

The triangle rule and the parallel quadrilateral rule are essentially the same, except that the triangle rule is simpler and the parallelogram is more widely used. For example, the parallelogram ABCD, AB and CD are opposite sides. In the vector BA+ vector BC, BC can be translated to BD, so it is the triangle rule.

Who can tell me when to use vector triangle and parallelogram rules? Who can tell me when to use vector triangles and parallelogram rules?

Does the parallelogram rule apply to all vector operations? What is the difference between a triangle rule and a parallelogram rule?

The angle between the plane vector b and the vector a=[1,-2] is 180 degrees and the module b is equal to 3 times the root number 5 to find the b vector coordinate

Given the vector a=(sin (/6),1), b=(4,4cosα-Root 3), if a⊥b, then sin (4π/3) is equal to A⊥b, then a*b=0 vector; sin (/6)+ cosα=√3/4 Sin (/3)=1/4, so sin (4π/3)=-1/4 How do you get sin (/6)+cosα=√3/4→sin (/3)=1/4
