Angle AOB with arbitrary points A and B on 2D plane Write a function named myfunction(x1.y1,x2.72) which accepts (x1.y1) and (x2.y2) as coordinates of two points A and B on the plane and returns the angle-AOB in DEGREE You can use any formulas or methods you like (google, math book, etc). Can check your codes with some special case for which you know the answer Hint somewhere you will need arc cosine in degree, acosd(), check it out on MATLAB first
